139-484: Vespa ( Italian pronunciation: [ˈvɛspa] ) is an Italian brand of scooters and mopeds manufactured by Piaggio . The name means wasp in Italian. The Vespa has evolved from a single model motor scooter manufactured in 1946 by Piaggio & Co. S.p.A. of Pontedera , Italy, to a full line of scooters and one of seven companies today owned by Piaggio. From their inception, Vespa scooters have been known for

278-442: A kick scooter with a seat, a floorboard, and small or low wheels. The US Department of Transportation defines a scooter as a motorcycle that has a platform for the operator's feet or has integrated footrests and has a step-through architecture. The classic scooter design features a step-through frame and a flat floorboard for the rider's feet. This design is possible because most scooter engines and drive systems are attached to

417-415: A power-valve system . The valves are normally in or around the exhaust ports. They work in one of two ways; either they alter the exhaust port by closing off the top part of the port, which alters port timing, such as Rotax R.A.V.E, Yamaha YPVS, Honda RC-Valve, Kawasaki K.I.P.S., Cagiva C.T.S., or Suzuki AETC systems, or by altering the volume of the exhaust, which changes the resonant frequency of

556-421: A rotary valve is that it enables the two-stroke engine's intake timing to be asymmetrical, which is not possible with piston-port type engines. The piston-port type engine's intake timing opens and closes before and after top dead center at the same crank angle, making it symmetrical, whereas the rotary valve allows the opening to begin and close earlier. Rotary valve engines can be tailored to deliver power over

695-458: A spare wheel . Many recent scooters use conventional front forks with the front axle fastened at both ends. Some jurisdictions do not differentiate between scooters and motorcycles. Though some jurisdictions classify smaller engine scooters (typically 50 cc or 3.1 cu in maximum) as moped class vehicles rather than motorcycles, meaning these scooters often have less stringent regulations (for example, 50 cc scooters can be driven with

834-557: A "foreign" machine. However, collectors prize the Cushman Vespa because it is relatively rare. Two expensive product-liability lawsuits, increased competition from Japanese scooters, and certain states' passing so-called "green laws" led to the bankruptcy of Vespa's American importer and the withdrawal of Vespa from the US market in late 1981. During 1981–2001, despite an absence of United States domestic sales, Vespas continued to have

973-462: A 50 cc in either two-stroke or four-stroke , up to a 150 cc four stroke. In 1959 Piaggio came under the control of the Agnelli family, the owners of car maker Fiat S.p.A. Vespa thrived until 1992 when Giovanni Alberto Agnelli became CEO, but Agnelli was already suffering from cancer and died in 1997. In 1999 Morgan Grenfell Private Equity acquired Piaggio, but a quickly hoped-for sale

1112-421: A DKW design that proved reasonably successful employing loop charging. The original SAAB 92 had a two-cylinder engine of comparatively low efficiency. At cruising speed, reflected-wave, exhaust-port blocking occurred at too low a frequency. Using the asymmetrical three-port exhaust manifold employed in the identical DKW engine improved fuel economy. The 750-cc standard engine produced 36 to 42 hp, depending on

1251-416: A car. Licensing requirements for scooters are easier and cheaper than for cars in most parts of the world, and insurance is usually cheaper. The term motor scooter is sometimes used to avoid confusion with kick scooter , but can then be confused with motorized scooter or e-scooter, a kick-scooter with an electric motor. The Shorter Oxford English Dictionary defines a motor scooter as a motorcycle similar to

1390-517: A core group of enthusiasts who kept vintage scooters on the road by rebuilding, restoring, and adding performance-enhancing engine parts as the stock parts would wear out. Vespa returned to the American market in 2001 with a new, more modern style ET series, in 50 cc two and four stroke, and 150 cc four-stroke. "These adjustments in engine power and the production of high-end “touring" Vespas make it apt for long-distance driving." According to

1529-448: A crossflow engine) is always best and support is good. In some engines, the small end is offset to reduce thrust in the intended rotational direction and the forward face of the piston has been made thinner and lighter to compensate, but when running backward, this weaker forward face suffers increased mechanical stress it was not designed to resist. This can be avoided by the use of crossheads and also using thrust bearings to isolate

1668-476: A few hundred such bikes were built, and the high price and technical difficulties made the venture a financial failure for both Wolfmüller and his financial backer, Hildebrand. In France, the Auto-Fauteuil was introduced in 1902. This was basically a step-through motorcycle with an armchair instead of a traditional saddle. Production continued until 1922. The motoped entered production in 1915, and

1807-417: A footboard, and is therefore not a scooter. Two-stroke engine A two-stroke (or two-stroke cycle ) engine is a type of internal combustion engine that completes a power cycle with two strokes of the piston (one up and one down movement) in one revolution of the crankshaft. (A four-stroke engine requires four strokes of the piston to complete a power cycle, in two crankshaft revolutions.) In

1946-420: A frame with mudguards and a casing covering the whole mechanical part". The basic patented design allowed a series of features to be deployed on the spar-frame that would later allow quick development of new models. The original Vespa featured a rear pillion seat for a passenger, or optionally a storage compartment. The original front protection "shield" was a flat piece of aero metal; later, this developed into

2085-649: A joint-venture with Piaggio in 1983, LML, in addition to being a large parts supplier for Piaggio, produced the P-Series scooters for the Indian market. In 1999, after protracted dispute with Piaggio, LML bought back Piaggio's stake in the company and the partnership ceased. LML continues to produce (and also exports) the P-Series variant known as the Stella in the U.S. market and by other names in different markets. Since

2224-422: A large parts supplier for Piaggio, produced the P-Series scooters for the Indian market . In 1999, after protracted dispute with Piaggio, LML bought back Piaggio's stake in the company and the partnership ceased. LML continued to produce (and also exported) the P-Series variant known as the Stella in the U.S. market and by other names in different markets. LML Factory which produced these P-Series variants issued

2363-539: A market to include some Commonwealth countries as well as the UK. It was a year which also saw the first meeting of the newly-formed Vespa scooter clubs with nearly 20,000 riders showing up for the event. Westinghouse took over Douglas in 1955, and while motorcycle production was stopped in 1957, Vespa production in Britain continued until 1965. Scooter (motorcycle) The global popularity of motor scooters dates from

2502-573: A normal car drivers license - or by adults aged 18+ years without any license (other than a valid liability insurance) at all as in case of at least Denmark - in many jurisdictions, and might pay less road-tax and be subject to less stringent roadworthiness testing). For all legal purposes in the United States of America, the National Highway Traffic Safety Administration (NHTSA) recommends using

2641-647: A notice of insolvency on 2 June 2017 and closed down permanently in 2018. In the 2012 Auto Expo held in New Delhi, the iconic Vespa re-entered the Indian market. Piaggio unveiled its range of scooters at the Expo. This became the first such venture of Piaggio in India without a local partner. Danmotor Vespa Indonesia (DMVI) was a joint venture between Indonesian interests and the East Asiatic Company, which

2780-484: A painted, pressed steel body which combines, in a unified structure: a full cowling enclosure around the engine concealing dirt or grease, a flat floor panel protecting the feet, and a prominent front fairing to divert wind and rain. After World War II, in light of its agreement to cease war activities with the Allies, Italy had its aircraft industry severely restricted in both capability and capacity. Piaggio emerged from

2919-633: A part of the former Nakajima Aircraft Company , began production of the Fuji Rabbit S-1 scooter in June 1946. Inspired by Powell scooters used by American servicemen, the S1 was designed to use surplus military parts, including the tailwheel of a Nakajima bomber, re-purposed as the front wheel of the S1. Later that year, Mitsubishi introduced the C10, the first of its line of Silver Pigeon scooters. This

3058-470: A patent in 1880 in Germany. The first truly practical two-stroke engine is attributed to Yorkshireman Alfred Angas Scott , who started producing twin-cylinder water-cooled motorcycles in 1908. Two-stroke gasoline engines with electrical spark ignition are particularly useful in lightweight or portable applications such as chainsaws and motorcycles. However, when weight and size are not an issue,

3197-399: A rechargeable battery. Petroleum hybrid-electric scooters are available. Electric scooters are rising in popularity because of higher gasoline prices, and battery technology is gradually improving, making this form of transportation more practical —the battery size is constrained by what the frame will fit, limiting range. An underbone is a motorcycle built on a chassis consisting mostly of

3336-449: A scavenging function. The units run in pairs, with the lower half of one piston charging an adjacent combustion chamber. The upper section of the piston still relies on total-loss lubrication, but the other engine parts are sump lubricated with cleanliness and reliability benefits. The mass of the piston is only about 20% more than a loop-scavenged engine's piston because skirt thicknesses can be less. Many modern two-stroke engines employ

3475-923: A scooter restoration industry, with many restored Vespas being exported from Thailand, Vietnam and Indonesia to the rest of the world. There is a Piaggio Museum & Gift Shop adjacent to the plant in central Pontedera, near Pisa, Tuscany. The permanent exhibition includes those items which toured venues such as the Guggenheim in New York and the Centre Pompidou in Paris. Also on display is a model personally customised by Salvador Dalí in 1962. The Miami Auto Museum in North Miami, Florida , claims to have largest collection of Vespa scooters with over 400 items. Vespa's largest market by all measures globally

3614-658: A similar system. Traditional flywheel magnetos (using contact-breaker points, but no external coil) worked equally well in reverse because the cam controlling the points is symmetrical, breaking contact before top dead center equally well whether running forward or backward. Reed-valve engines run backward just as well as piston-controlled porting, though rotary valve engines have asymmetrical inlet timing and do not run very well. Serious disadvantages exist for running many engines backward under load for any length of time, and some of these reasons are general, applying equally to both two-stroke and four-stroke engines. This disadvantage

3753-418: A single cylinder piston-port two-stroke engine , with four foot-operated gears and centrifugal fan cooling. The Maicoletta had a choice of engine sizes, approximately 175 cc (10.7 cu in), 250 cc (15 cu in), or 275 cc (16.8 cu in), The tubular frame was built on motorcycle principles, with long-travel telescopic forks and 14-inch (356 mm) wheels. The Maicoletta had

3892-528: A single large diameter tube. An underbone differs from a conventional motorcycle mainly by not having a structural member connecting the head stock to the structure under the front of the seat and by not having a fuel tank or similarly styled appendage in the space between the rider's knees. Underbones are commonly referred to as "step-throughs" and appeal to both genders in much the same way as scooters. Underbones are often mistaken for scooters and are sometimes marketed as such. However, an underbone does not have

4031-512: A spare wheel. Other features of the MP6 were similar to those on the Paperino, including the handlebar-mounted controls and the enclosed bodywork with the tall front splash guard. Upon seeing the MP6 for the first time, Enrico Piaggio exclaimed: "Sembra una vespa!" ("It looks like a wasp!") Piaggio effectively named his new scooter on the spot. Vespa is both Latin and Italian for wasp—derived from

4170-613: A spin on the Vespa. Vespa clubs popped up throughout Europe, and by 1952, worldwide Vespa Club membership had surpassed 50,000. By the mid-1950s, Vespas were being manufactured under licence in Germany, the United Kingdom, France, Belgium and Spain; in the 1960s, production was started in India, Brazil and Indonesia. By 1956, one million had been sold, then two million by 1960. By the 1960s, the Vespa—;originally conceived as

4309-516: A stress-bearing structure. The gear shift lever was moved to the handlebars for easier riding. The engine was placed near the rear wheel, eliminating the belt drive . The typical fork support was replaced by an arm similar to an aircraft carriage for easier tire-changing. The body design protected the driver from wind and road dirt. The smaller wheels and shorter wheelbase provide improved maneuverability through narrow streets and congested traffic. The name originated when Piaggio's president, upon seeing

4448-710: A tall central section that had to be straddled. Officially known as the MP5 ("Moto Piaggio no. 5"), the prototype was nicknamed "Paperino" (meaning "Donald Duck" in Italian). Piaggio was displeased with the MP5, especially the tall central section. He contracted aeronautical engineer Corradino D'Ascanio , to redesign the scooter. D'Ascanio, who had earlier been consulted by Ferdinando Innocenti about scooter design and manufacture, made it immediately known that he hated motorcycles, believing them to be bulky, dirty, and unreliable. D'Ascanio's MP6 prototype had its engine mounted beside

4587-436: A third of Piaggio and the mandate to run it. Chief executive Rocco Sabelli redesigned the factory to Japanese principles so that every Piaggio scooter could be made on any assembly line. In 2004 the company introduced a gas-electric hybrid scooter and a scooter with two wheels at the front and one at the back. Piaggio acquired scooter and motorcycle maker Aprilia in 2006 and in that same year Piaggio shares were launched onto

4726-626: A top speed of 70 mph (110 km/h) which was comparable with most 250 cc (15 cu in) motorcycles of the time. Other German scooters made by motorcycle manufacturers included the DKW Hobby, the Dürkopp Diana, and the TWN Contessa. In the United Kingdom, Douglas manufactured the Vespa under license from 1951 to 1961 and assembled them from 1961 to 1965. BSA and Triumph made several models of scooter including

4865-518: A turbocharger. Crankcase-compression two-stroke engines, such as common small gasoline-powered engines, are lubricated by a petroil mixture in a total-loss system . Oil is mixed in with their petrol fuel beforehand, in a fuel-to-oil ratio of around 32:1. This oil then forms emissions, either by being burned in the engine or as droplets in the exhaust, historically resulting in more exhaust emissions, particularly hydrocarbons, than four-stroke engines of comparable power output. The combined opening time of

5004-406: A twin skin to allow additional storage behind the front shield, similar to the glove compartment in a car. The fuel cap was located underneath the (hinged) seat, which saved the cost of an additional lock on the fuel cap or need for additional metal work on the smooth skin. The scooter had rigid rear suspension and small 8-inch (200 mm) wheels that allowed a compact design and plenty of room for

5143-525: A two-speed gearbox, but it is more notable for its full bodywork, similar to that which would appear of second- and third-generation scooters. The reputation of first-generation scooters was damaged by a glut of unstable machines with flexible frames, and more substantial examples like the Reynolds Runabout and the Unibus were too expensive to be competitive. The first generation had ended by

5282-867: A two-stroke engine, the end of the combustion stroke and the beginning of the compression stroke happen simultaneously, with the intake and exhaust (or scavenging ) functions occurring at the same time. Two-stroke engines often have a higher power-to-weight ratio than a four-stroke engine, since their power stroke occurs twice as often. Two-stroke engines can also have fewer moving parts , and thus be cheaper to manufacture and weigh less. In countries and regions with stringent emissions regulation, two-stroke engines have been phased out in automotive and motorcycle uses. In regions where regulations are less stringent, small displacement two-stroke engines remain popular in mopeds and motorcycles. They are also used in power tools such as chainsaws and leaf blowers . The first commercial two-stroke engine involving cylinder compression

5421-438: A utility vehicle—had come to symbolize freedom and imagination, and resulted in further sales boosts: four million by 1970, and ten million by the late 1980s. Improvements were made to the original design and new models were introduced. The 1948 Vespa 125 had rear suspension and a bigger engine. The headlamp was moved up to the handlebars in 1953 and had more engine power and a restyled rear fairing. A cheaper spartan version

5560-400: A wider speed range or higher power over a narrower speed range than either a piston-port or reed-valve engine. Where a portion of the rotary valve is a portion of the crankcase itself, of particular importance, no wear should be allowed to take place. In a cross-flow engine, the transfer and exhaust ports are on opposite sides of the cylinder, and a deflector on the top of the piston directs

5699-545: Is a sixth of the cost of a gasoline version. API were the first scooter manufacturers in India, with a Lambretta model in the 1950s. Bajaj Auto manufactured its line of scooters from 1972 to 2009, which included the Chetak , Legend , Super and Priya . The Chetak and Legend were based on the Italian Vespa Sprint . It was discontinued in 2009. Another Vespa partner in India was LML Motors . Beginning as

5838-413: Is accepted in most cases where cost, weight, and size are major considerations. The problem comes about because in "forward" running, the major thrust face of the piston is on the back face of the cylinder, which in a two-stroke particularly, is the coolest and best-lubricated part. The forward face of the piston in a trunk engine is less well-suited to be the major thrust face, since it covers and uncovers

5977-422: Is attributed to Scottish engineer Dugald Clerk , who patented his design in 1881. However, unlike most later two-stroke engines, his had a separate charging cylinder. The crankcase -scavenged engine, employing the area below the piston as a charging pump, is generally credited to Englishman Joseph Day . On 31 December 1879, German inventor Karl Benz produced a two-stroke gas engine, for which he received

6116-534: Is being phased out. Honda , for instance, ceased selling two-stroke off-road motorcycles in the United States in 2007, after abandoning road-going models considerably earlier. Due to their high power-to-weight ratio and ability to be used in any orientation, two-stroke engines are common in handheld outdoor power tools including leaf blowers , chainsaws , and string trimmers . Two-stroke diesel engines are found mostly in large industrial and marine applications, as well as some trucks and heavy machinery. Although

6255-612: Is believed to be the first motor scooter. They were followed that year by the Autoped , whose engine was engaged by pushing the handlebar column forward and whose brake was engaged by pulling the column back. Autopeds were made in Long Island , New York from 1915 to 1921, and were also made under license by Krupp in Germany from 1919 to 1922, following World War I . The number of scooter manufacturers and designs increased after World War I. The British - ABC Motors Skootamota ,

6394-574: Is common in on-road, off-road, and stationary two-stroke engines ( Detroit Diesel ), certain small marine two-stroke engines ( Gray Marine Motor Company , which adapted the Detroit Diesel Series 71 for marine use ), certain railroad two-stroke diesel locomotives ( Electro-Motive Diesel ) and large marine two-stroke main propulsion engines ( Wärtsilä ). Ported types are represented by the opposed piston design in which two pistons are in each cylinder, working in opposite directions such as

6533-729: Is largely done in Asia, with some assembly in Australia. The oldest scooter company in Australia is Vmoto , a Perth based company that started off importing and distributing scooters, but then started to manufacture its own electric scooters. Sydney based Hunted Scooters producers smaller numbers of niche petrol scooters, based on the customised Honda Ruckus scooters in Japan. More recently Sydney based Fonz Moto produce electric scooters and electric motorbikes , assembled in Australia, using overseas and Australian sourced components. Trends around

6672-465: Is still Italy, but as a result of the Mod subculture that developed in the 1960s, the United Kingdom is still Vespa's second largest global market—and at one point in the 1960s, its largest. The appeal of the Vespa to the style-conscious mods was the weather protection. Their counterparts, the rockers rode classic British motorcycles such as Triumph Bonneville and BSAs , and needed to wear leathers against

6811-432: Is that the two-stroke's crankcase is sealed and forms part of the induction process in gasoline and hot-bulb engines . Diesel two-strokes often add a Roots blower or piston pump for scavenging . The reed valve is a simple but highly effective form of check valve commonly fitted in the intake tract of the piston-controlled port. It allows asymmetric intake of the fuel charge, improving power and economy, while widening

6950-409: Is under every circumstance more efficient than cross-flow scavenging. In a uniflow engine, the mixture, or "charge air" in the case of a diesel, enters at one end of the cylinder controlled by the piston and the exhaust exits at the other end controlled by an exhaust valve or piston. The scavenging gas-flow is, therefore, in one direction only, hence the name uniflow. The design using exhaust valve(s)

7089-795: The Aprilia Mana 850 automatic-transmission motorcycle and the Honda NC700D Integra , which is a scooter built on a motorcycle platform. Some scooters, including the BMW C1 and the Honda Gyro Canopy , have a windscreen and a roof. The Piaggio MP3 offered a tall windscreen with roof as an option. With increasingly strict environmental laws , including United States emission standards and European emission standards , more scooters are using four-stroke engines again. Scooters may be powered by an electric motor powered by

7228-578: The Borsa Italiana with the listing symbol PIAGF. Piaggio first came back into the market in 2001 with the ET2 (two stroke 50 cc) and ET4 (four stroke 150 cc). In 2004, the PX (model year 2005) was reintroduced to North America to meet market demand for the classic Vespa design. Growth in the US market and worldwide environmental concerns meant a need for larger and cleaner engines, so Vespa developed

7367-540: The Burgman 400 and 650 models. Honda (600 cc or 37 cu in), Aprilia/Gilera (839 cc or 51.2 cu in), Yamaha (530 cc or 32 cu in), Kymco (700 cc or 43 cu in) and others have also introduced scooters with engine displacements ranging from 400 to 850 cc (24 to 52 cu in). Honda's PS250 (also known as Big Ruckus) features a motorcycle-like exoskeleton instead of bodywork. A new direction in maxi-scooters has

7506-464: The Junkers Jumo 205 and Napier Deltic . The once-popular split-single design falls into this class, being effectively a folded uniflow. With advanced-angle exhaust timing, uniflow engines can be supercharged with a crankshaft-driven blower, either piston or Roots-type. The piston of this engine is "top-hat"-shaped; the upper section forms the regular cylinder, and the lower section performs

7645-631: The Kenilworth , and the Reynolds Runabout debuted in 1919, with Gloucestershire Aircraft Company following with its Unibus in 1920. The Skootamota was noted for being practical, popular, and economical, the Kenilworth for its electric lights, and the Reynolds Runabout for its advanced specifications, including front suspension, a two-speed gearbox, leg shields, and a seat sprung with leaf springs and coil springs. The Unibus also had

7784-680: The Scomadi scooter, a retro styled UK designed and manufactured scooter. Scomadis were styled after classic Lambrettas. A number of different models at different capacity was produced. Production was later moved to Thailand. In Eastern Bloc countries scooters also became popular in the second half of 1950s, but their production was a result of planned economy rather than market competition. The Soviet Union started in 1957 with producing reverse engineered copies of 150 cc Vespa and 200 cc Glas Goggo as Vyatka and Tula T-200 respectively. They and their developments were manufactured in big numbers into

7923-512: The expansion chamber , such as the Suzuki SAEC and Honda V-TACS system. The result is an engine with better low-speed power without sacrificing high-speed power. However, as power valves are in the hot gas flow, they need regular maintenance to perform well. Direct injection has considerable advantages in two-stroke engines. In carburetted two-strokes, a major problem is a portion of the fuel/air mixture going directly out, unburned, through

8062-701: The gearshift and clutch control built into the left handlebar . Scooters usually feature bodywork, including a front leg shield and body that conceals all or most of the mechanicals. There is often some integral storage space, either under the seat, built into the front leg shield, or both. Scooters have varying engine displacements and configurations ranging from 50 cc (3.1 cu in) single-cylinder to 850 cc (52 cu in) twin-cylinder models. Traditionally, scooter wheels are smaller than conventional motorcycle wheels and are made of pressed steel or cast aluminum alloy, bolt on easily, and often are interchangeable between front and rear. Some scooters carry

8201-479: The oil reservoir does not depend on gravity. A number of mainstream automobile manufacturers have used two-stroke engines in the past, including the Swedish Saab , German manufacturers DKW , Auto-Union , VEB Sachsenring Automobilwerke Zwickau , VEB Automobilwerk Eisenach , and VEB Fahrzeug- und Jagdwaffenwerk , and Polish manufacturers FSO and FSM . The Japanese manufacturers Suzuki and Subaru did

8340-520: The 165 cc (10.1 cu in) Harley-Davidson Topper scooter were produced from 1960 to 1965 using the engine from their line of light motorcycles based on the DKW RT 125 . It had a fiberglass body, a continuously variable transmission , and a pull-cord starting mechanism. After World War II, wartime aircraft manufacturers were forbidden from making aircraft, and had to find other products to make in order to stay in business. Fuji Sangyo,

8479-416: The 1950s and 1960s. It was in production for about ten years, in three engine sizes, 150 cc (9.2 cu in), 175 cc (10.7 cu in) and 200 cc (12 cu in). They could perform all day at a steady speed of 60 mph (97 km/h). Extremely reliable and very well made, many of these scooters still exist today. Maico built the large Maicoletta scooter in the 1950s. It had

8618-528: The 1960s due in no small way to the increased power afforded by loop scavenging. An additional benefit of loop scavenging was the piston could be made nearly flat or slightly domed, which allowed the piston to be appreciably lighter and stronger, and consequently to tolerate higher engine speeds. The "flat top" piston also has better thermal properties and is less prone to uneven heating, expansion, piston seizures, dimensional changes, and compression losses. SAAB built 750- and 850-cc three-cylinder engines based on

8757-407: The 1960s, especially for motorcycles, but for smaller or slower engines using direct injection, the deflector piston can still be an acceptable approach. This method of scavenging uses carefully shaped and positioned transfer ports to direct the flow of fresh mixture toward the combustion chamber as it enters the cylinder. The fuel/air mixture strikes the cylinder head , then follows the curvature of

8896-438: The 1960s. It provided good weather protection with a full fairing, and the front wheel turned under a fixed nose extension. It had effective streamlining, perhaps thanks to its aircraft ancestry. Although it had only a 175 cc (10.7 cu in) four stroke motor, it could sustain speeds of 70 mph (110 km/h). Heinkel scooters were known for their reliability. Glas , a manufacturer of agricultural machinery, made

9035-539: The 1960s. They have recently started exporting to India for the first time (traditionally, that market was served by licensed Indian versions of the Vespa made by LML and Bajaj). Vespa produces some of its scooters in Vietnam, and has also sold its Italian ones there. Vespa scooters were sold beyond Europe and North America. When expanding into these markets it was common for Vespa to partner with, or license certain models to, existing manufacturers. Piaggio first licensed

9174-740: The 1970s, the lack of development cost Vespa, and like other markets, the sales fell off drastically in the economic boom of the 1980s. Then Vespa introduced the trendy automatic ET2, the city of London introduced the congestion charge and—partly with celebrity chef Jamie Oliver 's indirect help from his BBC2 TV series—sales suddenly leapt. Much as Vespa had used the Cushman Army scooter as inspiration for its original design, Vespa in turn made scooters for Sears, Roebuck & Company (labeled and marketed as "Allstate" scooters) and Cushman after World War II. Imported by Morton Colby of Colby General Tire Company, 662 East Fordham Road, Bronx, New York,

9313-596: The 1980s Japan, and latterly China and Taiwan, have become world leaders in the mass production of plastic bodied scooters, most often with "twist-and-go" type transmissions (where gear selection and clutch operation are fully automatic). A popular early model being the Honda Spree/Nifty Fifty . Advertising campaigns in the USA featured popular stars like Michael Jackson (Suzuki), and Grace Jones and Lou Reed (Honda), and sales of Japanese scooters peaked there in

9452-662: The 1980s. Both 2-stroke and 4-stroke plastic bodied scooters have been mass-produced in East Asia, with engine and transmission designs being either local designs or license built versions of European engines (eg Minarelli or Morini ). A popular 4-stroke engine in Chinese production is the GY6 engine , but electric motor-scooters are constantly increasing in the Chinese home market share. Unlike other countries, Australia had no major motorcycle companies, nor scooter manufacturers in

9591-412: The 1980s. In East Germany , IWL manufactured several own design 125 cc and 150 cc scooters (most notably SR 59 Berlin) from 1955 to 1964, when the authorities decided to switch the production to trucks. There were also produced small 50 cc Simson scooters, manufactured into the 1990s. From 1959 until 1965 there was produced the only Polish scooter, 150 cc to 175 cc WFM Osa . In Czechoslovakia, there

9730-483: The 50 cc model of 1963, and the largeframe scooters in 125 cc, 150 cc, 160 cc, 180 cc, and 200 cc displacements using engines derived from the redesigned 125 cc VNA engine from 1957. The largeframe Vespa evolved into the PX range in the late 1970s and was produced in 125, 150 and 200 cc versions until July 2007. Starting in 1981, an 80cc version was available as well. Piaggio reintroduced

9869-662: The BSA Dandy 70, the Triumph Tina , and the Triumph Tigress . The Tigress was made from 1959 to 1964 and was sold with a 175 cc 2-stroke single engine or a 250 cc 4-stroke twin; both versions used a foot-operated four-speed gearbox. The 250 twin had a top speed of 70 mph (110 km/h). The BSA Sunbeam was a badge engineered version of the Tigress. The early 2000's saw the small scale production of

10008-702: The C140 Silver Pigeon, while Fuji continued production of the Rabbit until the last of the S-211 series was built in June 1968. In post-World War II Italy the Piaggio Vespa became the standard for scooters, and has remained so for over 60 years. Patented in April 1946, it used aircraft design and materials. D'Ascanio's 98 cc (6.0 cu in) scooter had various new design concepts, including

10147-659: The Euro 3 automobile standards. Approximate parity with automobiles was achieved with NOx emissions in these studies. Emissions performance was tested on a g/km basis and was unaffected by fuel economy. In 2011 the United States Environmental Protection Agency allowed motorcycles, scooters, and mopeds with engine displacements less than 280 cc to emit ten times the NOx and six times the CO than

10286-585: The GT, offered as a 200 cc four-stroke and a 125 cc variant in Europe. In 2004, Vespa reintroduced a modernized PX 150 to the United States. In the fall of 2005, Piaggio offered their largest-selling Vespa scooter ever, the 250 cc-engined GTS250, available in Europe with ABS. In 2009, Vespa released the GTS 300 which can cruise at 105–113 km/h (65–70 mph). Vespa have exported Scooters to Australia since

10425-452: The German inventor of an early form in the mid-1920s, it became widely adopted in Germany country during the 1930s and spread further afield after World War II . Loop scavenging is the most common type of fuel/air mixture transfer used on modern two-stroke engines. Suzuki was one of the first manufacturers outside of Europe to adopt loop-scavenged, two-stroke engines. This operational feature

10564-528: The Goggo scooter from 1951 to 1955. Glas discontinued scooter production to concentrate on its Goggomobil microcar . Several manufacturers in the German motorcycle industry made scooters. NSU made Lambrettas under license from 1950 to 1955, during which they developed their Prima scooter. Production of the Prima began when NSU's license to build Lambrettas ran out. Zündapp made the popular Bella scooter in

10703-453: The LEADER (Low Emissions ADvanced Engine Range) series of four-stroke engines. The larger Granturismo frame, with larger 12-inch (300 mm) wheels, was introduced to handle the additional power. The bike in 2006 spawned the iconic GTS-250ie version, with an upgraded suspension and the new QUASAR (QUArter-liter Smooth Augmented Range) 250 cc fuel-injected engine, capable of 80+ mph. As of

10842-524: The Model 39, a three-wheeled utility scooter with a large storage bin between the front wheels. They sold 606 to the US military during the war. The Piaggio MP3 and Yamaha Tricity are modern tilting three-wheeled scooters. Unlike most motorcycle trikes, they are reverse trikes, with two front wheels which steer, and a single driven rear wheel. The front suspension allows both front wheels to tilt independently, so that all three wheels remain in contact with

10981-773: The Motorcycle Industry Council, U.S. scooter sales increased fivefold over six years, swelling from 12,000 units in 1997 to 69,000 units in 2002. Vespa sales in the U.S. increased 27 percent between 2001 and 2002. The 65 "Vespa Boutiques" scattered throughout the U.S. gave scooterists a place to buy, service, and customize Vespa scooters, and outfit themselves in everything from Vespa watches and helmets to Vespa jackets, T-shirts, and sunglasses. Vespa restarted its American sales effort, opening its first boutique on Ventura Boulevard in Sherman Oaks, California . In light of vastly-increasing US sales, Vespa developed

11120-512: The PX 125 and 150 models in 2011, with a revised EURO3 compliant engine. The smallframe evolved into the PK range in the early 1980s, although some vintage-styled smallframes were produced for the Japanese market as late as the mid-1990s. The ET model range stuck true to the wasp/aero design principles. It was lighter, more aerodynamic, had an automatic gearbox and could take a series of engines from

11259-537: The Sears models were 3- and 4-speed 125 cc Vespas rebadged as Sears Allstate Cruiseaires . Innocenti also distributed their Lambretta brand via Montgomery Ward 's catalogue during this post-World War II period. These were the premier brands of scooters, bringing premium pricing to many, including farmers, whose link to the outside world was via purchases made in these catalogues. Cushman sold rebadged Vespa scooters as Cushmans, but many Cushman dealers refused to market

11398-510: The Vespa's low running costs are two reasons for the increase in Vespa (and other scooter) popularity. The cultural use of the scooter as a recreational vehicle with a sub-cultural following in the US, Canada and parts of Europe and Japan has also contributed to the rise in Vespa ownership. In contrast, the Vespa is considered a utilitarian vehicle for hauling products and sometimes up to 5 family members in much of Asia and Mexico. This resurgence in interest in vintage motor scooters has also spawned

11537-423: The bore diameter for reasonable piston ring life. Beyond this, the piston rings bulge into the exhaust port and wear quickly. A maximum 70% of bore width is possible in racing engines, where rings are changed every few races. Intake duration is between 120 and 160°. Transfer port time is set at a minimum of 26°. The strong, low-pressure pulse of a racing two-stroke expansion chamber can drop the pressure to -7 psi when

11676-474: The city due to air pollution . Scooter-like traits began to develop in motorcycle designs around the 1900s. In 1894, Hildebrand & Wolfmüller in Munich , Germany produced the first motorcycle that was available for purchase. Their motorcycle had a step-through frame, with its fuel tank mounted on the down tube, its parallel two-cylinder engine mounted low on the frame, and its cylinders mounted in line with

11815-459: The combustion chamber, and then is deflected downward. This not only prevents the fuel/air mixture from traveling directly out the exhaust port, but also creates a swirling turbulence which improves combustion efficiency , power, and economy. Usually, a piston deflector is not required, so this approach has a distinct advantage over the cross-flow scheme (above). Often referred to as "Schnuerle" (or "Schnürle") loop scavenging after Adolf Schnürle,

11954-560: The company was located at a purpose-built factory in Pulo Gadung . This was greatly expanded in 1977 to also manufacture sub-components, following a government decree that a higher domestically-built proportion of these should be used. Sub-components were also bought from other Indonesian manufacturers after their quality had been approved by Piaggio. Vespa has had various partnerships and presence in Taiwan. In 1965, Taiwan Vespa Co. Ltd

12093-408: The conflict with its Pontedera bomber plane plant demolished by bombing. Italy's crippled economy, and the disastrous state of its roads, were not immediately conducive to the redevelopment of the automobile market. Enrico Piaggio , the son of Piaggio's founder Rinaldo Piaggio, decided to leave the aeronautical field to address Italy's urgent need for a modern and affordable mode of transportation for

12232-453: The crankshaft commonly spins in the same axis and direction as do the wheels i.e. "forward". Some of the considerations discussed here apply to four-stroke engines (which cannot reverse their direction of rotation without considerable modification), almost all of which spin forward, too. It is also useful to note that the "front" and "back" faces of the piston are - respectively - the exhaust port and intake port sides of it, and are not to do with

12371-415: The cycle's potential for high thermodynamic efficiency makes it ideal for diesel compression ignition engines operating in large, weight-insensitive applications, such as marine propulsion , railway locomotives , and electricity generation . In a two-stroke engine, the exhaust gases transfer less heat to the cooling system than a four-stroke, which means more energy to drive the piston, and if present,

12510-502: The design to several European manufacturers including Piaggio. The Motor Glide set the standards for all later models. It inspired production of motor scooters by Powell , Moto-scoot, Cushman, Rock-Ola, and others. The Cushman Company produced motor scooters from 1936 to 1965. Cushman was an engine manufacturer that started making scooters after Salsbury found their offer to supply engines to be unacceptable. Cushman and Salsbury competed against each other, with both companies advertising

12649-582: The economy of their scooters. Cushman claimed an efficiency of 120 mpg ‑US (2.0 L/100 km; 140 mpg ‑imp ) at 30 mph (48 km/h). Cushman introduced a centrifugal clutch to their scooters in 1940. The Cushman Auto Glide Model 53 was designed to be dropped by parachute with Army Airborne troops, and was eventually called the "Cushman Airborne". Cushman scooters were also used around military bases for messenger service. Salsbury continued manufacturing scooters until 1948, while Cushman continued until 1965. Small numbers of

12788-480: The elements. Mods would modify their Vespas, adding lights, mascots, accessories, various racks and crash bars. A new lifestyle evolved in the UK, with thousands attending scooter rallies . The dominance of the Vespa declined through the 1970s, as small car ownership increased and cheap and reliable commuter bikes like the Honda Super Cub hit sales. Despite the introduction of the more modern 'P' range in

12927-606: The end of 2010 the GTS 250 has been replaced by the GTS 300 which has a 278cc fuel – injected engine. In 2005, the ET was withdrawn from Europe and North America and replaced by a new small-frame scooter, the LX range. These were available in the US in 50 cc and 150 cc versions, while Europeans could choose a 50 cc, 125 cc and 150 cc. In recent years, many urban commuters have purchased new or restored Vespas. A shortage of available parking for automobiles in large urban areas and

13066-399: The engine fixed to the frame. This arrangement improves handling by allowing bigger wheels and less unsprung weight, also tending to move the centre of gravity forwards. The trend toward larger, more powerful scooters with fully automatic transmissions converges with an emerging trend in motorcycle design that foreshadows automatic transmission motorcycles with on-board storage. Examples include

13205-400: The engine from end loads. Large two-stroke ship diesels are sometimes made to be reversible. Like four-stroke ship engines (some of which are also reversible), they use mechanically operated valves, so require additional camshaft mechanisms. These engines use crossheads to eliminate sidethrust on the piston and isolate the under-piston space from the crankcase. On top of other considerations,

13344-407: The engine's spark) to push air over the cylinder's cooling fins. The modern Vespa engine is still cooled this way. The MP6 prototype had large grilles on the front and rear of the rear fender covering the engine. This was done to allow air in to cool the engine, as the prototype did not have fan cooling. A cooling fan similar to that used on the MP5 "Paperino" prototype was included in the design of

13483-415: The exhaust port in the cylinder, the hottest part of the engine, where piston lubrication is at its most marginal. The front face of the piston is also more vulnerable since the exhaust port, the largest in the engine, is in the front wall of the cylinder. Piston skirts and rings risk being extruded into this port, so having them pressing hardest on the opposite wall (where there are only the transfer ports in

13622-409: The exhaust port, and direct injection effectively eliminates this problem. Two systems are in use: low-pressure air-assisted injection and high-pressure injection. Since the fuel does not pass through the crankcase, a separate source of lubrication is needed. For the purpose of this discussion, it is convenient to think in motorcycle terms, where the exhaust pipe faces into the cooling air stream, and

13761-485: The feature film Roman Holiday for a ride through Rome, resulting in over 100,000 sales. In 1956, John Wayne dismounted his horse in favor of the two-wheeler to originally get between takes on sets. as well as Marlon Brando , Dean Martin , and the entertainer Abbe Lane had become Vespa owners. William Wyler filmed Ben Hur in Rome in 1959, allowing Charlton Heston to abandon horse and chariot between takes to take

13900-418: The frame. It was water-cooled and had a radiator built into the top of the rear fender. It became the first mass-produced and publicly sold powered two-wheel vehicle, and among the first powered mainly by its engine rather than foot pedals. Maximum speed was 40 km/h (25 mph). The rear wheel was driven directly by rods from the pistons in a manner similar to the drive wheels of steam locomotives . Only

14039-413: The fresh intake charge into the upper part of the cylinder, pushing the residual exhaust gas down the other side of the deflector and out the exhaust port. The deflector increases the piston's weight and exposed surface area, and the fact that it makes piston cooling and achieving an effective combustion chamber shape more difficult is why this design has been largely superseded by uniflow scavenging after

14178-522: The ground as it leans when cornering. A maxi-scooter or touring scooter is a large scooter, with engines ranging in size from 150 to 850 cc (9.2 to 51.9 cu in), and using larger frames than normal scooters with longer wheelbases. Typically, the dash is fixed & is not mounted on the handlebars. The trend toward maxi-scooters began in 1986 when Honda introduced the CN250 Helix / Fusion / Spazio. Many years later, Suzuki launched

14317-443: The intake and exhaust ports in some two-stroke designs can also allow some amount of unburned fuel vapors to exit in the exhaust stream. The high combustion temperatures of small, air-cooled engines may also produce NO x emissions. Two-stroke gasoline engines are preferred when mechanical simplicity, light weight, and high power-to-weight ratio are design priorities. By mixing oil with fuel, they can operate in any orientation as

14456-459: The masses. In 2024 Piaggio celebrated 140 years with limited edition of 'Vespa 140th of Piaggio,' with only 140 units available from 18 to 21 April 2024. In 1944 Piaggio engineers Renzo Spolti and Vittorio Casini designed a motorcycle with bodywork fully enclosing the drivetrain and forming a tall splash guard at the front. In addition to the bodywork, the design included handlebar-mounted controls, forced air cooling, wheels of small diameter, and

14595-485: The median Tier II bin 5 automobile regulations. An additional air quality challenge can also arise from the use of moped and scooter transportation over automobiles, as a higher density of two-wheeled vehicles can be supported by existing transportation infrastructure. In Genoa, 2-stroke engine scooters made before 1999 are banned since 2019. In some cities, such as Shanghai , petrol scooters/mopeds are banned and only LPG or electric scooters are allowed to be used in

14734-624: The mid-1920s. E. Foster Salsbury and Austin Elmore developed the Salsbury Motor Glide, which was a division of Northrop Aircraft , a scooter with a seat above an enclosed drivetrain, and began production in 1936 in California. In 1938, Salsbury introduced a more powerful scooter with a continuously variable transmission (CVT). This was the first use of a CVT on a scooter. It was such a success that Salsbury attempted to license

14873-475: The model year. The Monte Carlo Rally variant, 750-cc (with a filled crankshaft for higher base compression), generated 65 hp. An 850-cc version was available in the 1966 SAAB Sport (a standard trim model in comparison to the deluxe trim of the Monte Carlo). Base compression comprises a portion of the overall compression ratio of a two-stroke engine. Work published at SAE in 2012 points that loop scavenging

15012-399: The oil pump of a modern two-stroke may not work in reverse, in which case the engine suffers oil starvation within a short time. Running a motorcycle engine backward is relatively easy to initiate, and in rare cases, can be triggered by a back-fire. It is not advisable. Model airplane engines with reed valves can be mounted in either tractor or pusher configuration without needing to change

15151-421: The original hey day of scooters in the 1950s and 1960s. Scooters were mostly traditionally imported from Italy, and then in the 1970s and 1980s, from Japan and Asia. Australian scooters have only appeared in the last 20 years or so, and many of them relating to the recent advent and viability of the electric engine. Australian scooter companies design, market and manage the company from Australia, but manufacturing

15290-487: The other - the inlet pipe having passage to the crankcase only when the two cutouts coincide. The crankshaft itself may form one of the members, as in most glow-plug model engines. In another version, the crank disc is arranged to be a close-clearance fit in the crankcase, and is provided with a cutout that lines up with an inlet passage in the crankcase wall at the appropriate time, as in Vespa motor scooters. The advantage of

15429-434: The piston covering and uncovering the ports as it moves up and down in the cylinder. In the 1970s, Yamaha worked out some basic principles for this system. They found that, in general, widening an exhaust port increases the power by the same amount as raising the port, but the power band does not narrow as it does when the port is raised. However, a mechanical limit exists to the width of a single exhaust port, at about 62% of

15568-440: The piston is at bottom dead center, and the transfer ports nearly wide open. One of the reasons for high fuel consumption in two-strokes is that some of the incoming pressurized fuel-air mixture is forced across the top of the piston, where it has a cooling action, and straight out the exhaust pipe. An expansion chamber with a strong reverse pulse stops this outgoing flow. A fundamental difference from typical four-stroke engines

15707-617: The post-World War II introductions of the Vespa and Lambretta models in Italy. These scooters were intended to provide economical personal transportation ( engines from 50 to 150 cc or 3.1 to 9.2 cu in). The original layout is still widely used in this application. Maxi-scooters , with larger engines from 200 to 850 cc (12 to 52 cu in) have been developed for Western markets. Scooters are popular for personal transportation partly due to being more affordable, easier to operate, and more convenient to park and store than

15846-550: The power band. Such valves are widely used in motorcycle, ATV, and marine outboard engines. The intake pathway is opened and closed by a rotating member. A familiar type sometimes seen on small motorcycles is a slotted disk attached to the crankshaft , which covers and uncovers an opening in the end of the crankcase, allowing charge to enter during one portion of the cycle (called a disc valve). Another form of rotary inlet valve used on two-stroke engines employs two cylindrical members with suitable cutouts arranged to rotate one within

15985-466: The principles remain the same, the mechanical details of various two-stroke engines differ depending on the type. The design types vary according to the method of introducing the charge to the cylinder, the method of scavenging the cylinder (exchanging burnt exhaust for fresh mixture) and the method of exhausting the cylinder. Piston port is the simplest of the designs and the most common in small two-stroke engines. All functions are controlled solely by

16124-531: The production Vespa, and the grilles were removed from the fender. Piaggio filed a patent for the Vespa scooter design in April 1946. The application documents referred to a "model of a practical nature" for a "motorcycle with rationally placed parts and elements with a frame combining with mudguards and engine-cowling covering all working parts", of which "the whole constitutes a rational, comfortable motorcycle offering protection from mud and dust without jeopardizing requirements of appearance and elegance". The patent

16263-442: The production of Vespa scooters in India to Bajaj Auto in the 1960s. In 1971, Piaggio's license was not renewed as a part of then Prime Minister Indira Gandhi 's privatization programs. After the collaboration ended, Bajaj continued to produce scooters based on the Vespa design, namely the Chetak . Another Vespa partner in India was that of LML Motors . Beginning as a joint-venture with Piaggio in 1983, LML, in addition to being

16402-687: The prototype, remarked "Sembra una vespa" , "It looks like a wasp". Months after the Vespa, in 1947, Innocenti introduced the Lambretta , beginning a rivalry with Vespa. The scooter was designed by Innocenti, his General Director Giuseppe Lauro and engineer Pierluigi Torre. The Lambretta was named after Lambrate, the Milanese neighborhood where the factory stood. It debuted in 1947 at the Paris Motor Show. The Lambretta 'A' went on sale on December 23, 1947, and sold 9,000 units in one year. It

16541-419: The rear axle or under the seat. Unlike a conventional motorcycle, in which the engine is mounted on the frame, most modern scooters allow the engine to swing with the rear wheel, while most vintage scooters and some newer retro models have an axle-mounted engine. Modern scooters starting from the late-1980s generally use a continuously variable transmission (CVT), while older ones use a manual transmission with

16680-527: The rear wheel. The wheel was driven directly from the transmission, eliminating the drive chain and the oil and dirt associated with it. The prototype had a unit spar frame with stress-bearing steel outer panels. These changes allowed the MP6 to have a step-through design instead of a tall centre section like that of the MP5 Paperino. The MP6 design also included a single-sided front suspension, interchangeable front and rear wheels mounted on stub axles, and

16819-411: The rider's legs. The Vespa's enclosed, horizontally mounted 98 cc two-stroke engine acted directly on the rear drive wheel through a three-speed transmission. The twistgrip -controlled gear change involved a system of rods. The early engine had no forced-air cooling, but fan blades were soon attached to the magneto -flywheel (which houses the points and generates electricity for accessories and for

16958-821: The same in the 1970s. Production of two-stroke cars ended in the 1980s in the West, due to increasingly stringent regulation of air pollution . Eastern Bloc countries continued until around 1991, with the Trabant and Wartburg in East Germany. Two-stroke engines are still found in a variety of small propulsion applications, such as outboard motors , small on- and off-road motorcycles , mopeds , motor scooters , motorized bicycles , tuk-tuks , snowmobiles , go-karts , RC cars , ultralight and model airplanes. Particularly in developed countries, pollution regulations have meant that their use for many of these applications

17097-407: The subject of multiple studies. Studies have found that two-stroke 50  cc mopeds, with and without catalytic converters, emit ten to thirty times more hydrocarbons and particulate emissions than the outdated Euro 3 automobile standards. In the same study, four-stroke mopeds, with and without catalytic converters, emitted three to eight times more hydrocarbons and particulate emissions than

17236-462: The term motorcycle for all of these vehicles. However, while NHTSA excludes the term motor scooter from legal definition, it proceeds, in the same document, to give detailed instructions on how to import a small motor scooter. As of 2020 the US state of California has a regulatory system for 2- and 3-wheeled vehicles. It classifies vehicles with fewer than four wheels into the following categories: The emissions of mopeds and scooters have been

17375-520: The top or bottom of the piston. Regular gasoline two-stroke engines can run backward for short periods and under light load with little problem, and this has been used to provide a reversing facility in microcars , such as the Messerschmitt KR200 , that lacked reverse gearing. Where the vehicle has electric starting, the motor is turned off and restarted backward by turning the key in the opposite direction. Two-stroke golf carts have used

17514-511: The vehicle's body shape: the thicker rear part connected to the front part by a narrow waist, and the steering rod resembled antennae . On 23 April 1946 at 12 o'clock in the central office for inventions, models and makes of the Ministry of Industry and Commerce in Florence , Piaggio e C. S.p.A. took out a patent for a "motorcycle of a rational complexity of organs and elements combined with

17653-505: The world have seen new developments of the classic scooter, some with larger engines and tires. High-end scooter models now include comprehensive technological features, including cast aluminium frames, engines with integral counterbalancing, and cross-linked brake systems. Some of these scooters have comfort features such as an alarm, start button, radio, windshield , heated hand grips and full instrumentation (including clock or outside temperature gauge). During World War II, Cushman made

17792-409: Was aiming to manufacture the new Vespa in large numbers, and their longstanding industrial experience led to an efficient Ford-style volume production line. The scooter was presented to the press at Rome Golf Club, where journalists were apparently mystified by the strange, pastel coloured, toy-like object on display. However, the road tests were encouraging, and even with no rear suspension the machine

17931-477: Was also available. One of the best-loved models was the Vespa 150 GS introduced in 1955 with a 150 cc engine, a long saddle, and the faired handlebar-headlamp unit. Then came the 50 cc of 1963, and in 1968 Vespa 125 Primavera became one of the most durable of all. Vespas came in two sizes, referred to as "largeframe" and "smallframe". The smallframe scooters came in 50 cc, 90 cc, 100 cc, and 125 cc versions, all using an engine derived from

18070-433: Was also dismantled after World War II. Heinkel stayed in business by making bicycles and mopeds, while Messerschmitt made sewing machines and automobile parts. Messerschmitt took over the German license to manufacture Vespa scooters from Hoffman in 1954 and built Vespas under from 1954 to 1964. Heinkel designed and built its own scooters. The Heinkel Tourist was a large and relatively heavy touring scooter produced in

18209-421: Was approved the following December. The first 13 examples appeared in spring 1946, and revealed their aeronautical background. In the first examples, one can recognize the typical aircraft technology. Attention to aerodynamics is evident in all the design, in particular on the tail. It was also one of the first vehicles to use monocoque construction (where the body is an integral part of the chassis). The company

18348-559: Was based in Denmark. Between 1972 and 2001, it produced Vespas under license for the Indonesian market. In 1976 approximately 40,000 units were produced giving DMVI the third biggest share of the Indonesian scooter market. Government tax incentives allowed these scooters to be exported to Thailand at less than the domestic market price, so that they would be economically competitive. DMVI only built 90 and 150cc models. From 1972 onwards

18487-655: Was dashed by a failed joint venture in China. By 2003 the company found itself close to bankruptcy. Continual management changes and great sums spent on many different plans and products had saddled Piaggio with debt and left it vulnerable to competition from cheaper Asian rivals. Despite this, the brand was still well-known and products like the Vespa ET4 were gaining positive publicity. In October 2003 Roberto Colaninno made an initial investment of €100 million through his holding company Immsi S.p.A. in exchange for just under

18626-490: Was efficient, at a time when fuel was severely rationed. It had a top speed of 45 mph (72 km/h) from a fan-cooled engine of 123 cc (7.5 cu in). The first Lambretta designs had shaft drive and no rear suspension, later designs used various drive and suspension systems until Lambretta settled on a swingarm-mounted engine with chain drive. Also other Italian firms manufactured scooters in 1950s and 1960s, like Italjet and Iso . Germany's aviation industry

18765-713: Was inspired by a Salsbury Motor Glide that had been brought to Japan by a Japanese man who had lived in the United States. Production of the Mitsubishi Silver Pigeon and the Fuji Rabbit continued through several series until the 1960s. Some series of the Fuji Rabbit were developed to a high level of technological content; the S-601 Rabbit Superflow had an automatic transmission with a torque converter, an electric starter, and pneumatic suspension. Mitsubishi ended scooter production with

18904-468: Was licensed for Vespa scooter production. From 1972 to 1982, Vespa entered into a collaboration with scooter manufacturer PGO . In 1978, Vespa entered into a collaboration with TGB , which to some extent, continues to this day (namely with CVT transmission production). In 1951 the financially troubled motorcycle manufacturer Douglas started production of Piaggio licensed Vespa scooters in Bristol , with

19043-440: Was more manoeuvrable and comfortable to ride than a traditional motorcycle. Following its public debut at the 1946 Milan Fair, the first fifty sold slowly.
