62-494: The Harley-Davidson WLA is a Harley-Davidson motorcycle that was produced to US Army specifications in the years during and around World War II. It was based on an existing civilian model, the WL , and is of the 45 solo type, so called due to its 45-cubic-inch (740 cm) engine displacement and single-rider design. It acquired the nickname " Liberator ". The model number breaks down as follows: Harley-Davidson began producing
124-532: A Harley-Davidson like he saw or rode in the service, leading to the post-war popularity of both the motorcycle and the company in general. However, this also ensured that few nearly-original WLAs would survive in the US or even Western Europe. A significant number of WLAs were left in the Soviet Union, and either stored or put in private hands. With little access to parts and no chopper culture, and no export path to
186-471: A commemorative model in 1991. By 1990, with the introduction of the "Fat Boy" , Harley-Davidson once again became the sales leader in the heavyweight (over 750 cc) market. At the time of the Fat Boy model introduction, a false etymology spread that "Fat Boy" was a combination of the names of the atomic bombs Fat Man and Little Boy . This has been debunked, as the name "Fat Boy" actually comes from
248-732: A company-sponsored, brand-focused museum. Harley-Davidson is noted for a style of customization that gave rise to the chopper motorcycle style. The company traditionally marketed heavyweight, air-cooled cruiser motorcycles with engine displacements greater than 700 cc, but it has broadened its offerings to include more contemporary VRSC (2002) and middle-weight Street (2014) platforms. Harley-Davidson manufactures its motorcycles at factories in York, Pennsylvania ; Menomonee Falls, Wisconsin ; Tomahawk, Wisconsin ; Manaus , Brazil; and Rayong , Thailand . The company markets its products worldwide, and also licenses and markets merchandise under
310-586: A front brake in 1928, although only on the J/JD models. In the late summer of 1929, Harley-Davidson introduced its 45-cubic-inch (737 cc) flathead V-Twin to compete with the Indian 101 Scout and the Excelsior Super X . This was the "D" model produced from 1929 to 1931. Riders of Indian motorcycles derisively referred to it as the "three cylinder Harley" because the generator was upright and parallel to

Construction started on the $ 75 million, 130,000 square-foot (12,000 m ) Harley-Davidson Museum in the Menomonee Valley of Milwaukee, Wisconsin on June 1, 2006. It opened in 2008 and houses the company's vast collection of historic motorcycles and corporate archives, along with
434-571: A longitudinal V-twin shaft-drive model, the Indian 841 . Harley-Davidson would later produce the MT350E , after acquiring the British Armstrong company in 1987. These were dual-sport machines, capable of both on-road and off-road service, powered by 350 cc Rotax engines. The MT350E was a redesign of the 500 cc Armstrong MT500 , which reduced weight, added an electric start, and upgraded pollution standards. The MT500 began as
496-790: A market that has been important to them ever since. In 1907, William A. Davidson quit his job as tool foreman for the Milwaukee Road railroad and joined the Motor Company. Production in 1905 and 1906 were all single-cylinder models with 26.84-cubic-inch (440 cc) engines. In February 1907, they displayed a prototype model at the Chicago Automobile Show with a 45-degree V-Twin engine. Very few V-Twin models were built between 1907 and 1910. These first V-Twins displaced 53.68 cubic inches (880 cc) and produced about 7 horsepower (5.2 kW). This gave about double
558-584: A restaurant, café and meeting space. Established in 1918, the oldest continuously operating Harley-Davidson dealership outside of the United States is in Australia. Sales in Japan started in 1912 then in 1929, Harley-Davidsons were produced in Japan under license to the company Rikuo (Rikuo Internal Combustion Company) under the name of Harley-Davidson and using the company's tooling, and later under
620-504: A semi-step-through frame and tank. The M-65S was a M-65 with a larger tank that eliminated the step-through feature. The Rapido was a larger bike with a 125 cc engine. The Aermacchi-built Harley-Davidsons became entirely two-stroke powered when the 250 cc two-stroke SS-250 replaced the four-stroke 350 cc Sprint in 1974. Harley-Davidson purchased full control of Aermacchi 's motorcycle production in 1974 and continued making two-stroke motorcycles there until 1978, when they sold
682-482: A specific motor accurately, and some other parts bear year and month stamps. Frames and many other parts were not tagged with the serial number, but can be dated by castingnumbers. This is common prior to adoption of the vehicle identification number (VIN). Many WLAs would be shipped to allies under the Lend-Lease program. The largest recipient was the Soviet Union, which was sold over 30,000 WLAs. Production of

The three began work on a new and improved machine with an engine of 24.74 cubic inches (405 cc) with 9.75 in (24.8 cm) flywheels weighing 28 lb (13 kg). Its advanced loop-frame pattern was similar to the 1903 Milwaukee Merkel motorcycle designed by Joseph Merkel, later of Flying Merkel fame. The bigger engine and loop-frame design took it out of
806-541: Is an odorless, colorless liquid. Like other short-chained alkanes with a low molecular weight, it is volatile , flammable, and toxic. Octane is 1.2 to 2 times more toxic than heptane . N-octane has 23 constitutional isomers . 8 of these isomers have one stereocenter ; 3 of them have two stereocenters. Achiral Isomers: Chiral Isomers: In petrochemistry, octanes are not typically differentiated or purified as specific compounds. Octanes are components of particular boiling fractions. A common route to such fractions
868-553: Is one of two major American motorcycle manufacturers to survive the Great Depression along with its historical rival, Indian Motorcycles . The company has survived numerous ownership arrangements, subsidiary arrangements, periods of poor economic health and product quality, and intense global competition to become one of the world's largest motorcycle manufacturers and an iconic brand widely known for its loyal following. There are owner clubs and events worldwide, as well as
930-515: The ELA and ELC , as well as an Army version of the U , the UA . There was also an experimental three-wheeler TA with a 69 ci EL-motor. These were produced mainly for "home front" use, and not in very large numbers. Consequently, they are very rare today. Indian , Harley-Davidson's major competitor at the time, also produced some war-time models, such as the Indian 640 , Indian CAV/340 , Indian 741 , and
992-547: The Lend-Lease program numbered at least 30,000. The WLAs produced during all four years of war production generally have 1942 serial numbers. Production of the WLA stopped at the end of World War II, but was resumed from 1950 to 1952 for use in the Korean War . The U.S. Army also asked Harley-Davidson to produce a new motorcycle with many of the features of BMW's side-valve and shaft-driven R71. Harley-Davidson largely copied
1054-484: The University of Wisconsin–Madison with a degree in mechanical engineering. That year, they expanded the factory with a second floor and later with facings and additions of Milwaukee pale yellow ("cream") brick. With the new facilities, production increased to 150 motorcycles in 1907. The company was officially incorporated that September. They also began selling their motorcycles to police departments around this time,
1116-730: The XA based closely on the BMW. About 1,000 were produced. Due to its new features and low production, the XA was expensive, and by that time it was clear that the Jeep was the Army's general purpose vehicle of choice; the less advanced but cheaper WLA was considered sufficient for its limited roles. Other motorcycles produced by HD for World War II included US Army and Canadian versions of the Big Twin EL family,
1178-453: The chemical formula C 8 H 18 , and the condensed structural formula CH 3 (CH 2 ) 6 CH 3 . Octane has many structural isomers that differ by the location of branching in the carbon chain . One of these isomers, 2,2,4-trimethylpentane (commonly called iso-octane), is used as one of the standard values in the octane rating scale. Octane is a component of gasoline and petroleum. Under standard temperature and pressure , octane
1240-615: The "small twin" flathead design was popular in applications needing low cost and reliability more than power. This engine remained in production from 1937 to 1973 in the Servi-Car , although it was superseded in two-wheeled motorcycles by the more advanced flathead engine used in the Model K in 1952, the short-lived ancestor engine of the OHV Sportster from 1957. Though the model designation suggested high compression, for reliability,
1302-603: The 74-cubic-inch "Knucklehead" was introduced as the F and the FL . The 80 cu in (1,300 cm ) flathead UH and ULH models were discontinued after 1941, while the 74-cubic-inchU & UL flathead models were produced up to 1948. One of only two American motorcycle manufacturers to survive the Great Depression (the other being the Indian Motorcycle Manufacturing Company ), Harley-Davidson again produced large numbers of motorcycles for

#17327874228101364-401: The Army version actually used a medium-compression version. In modern terms, the WLA's compression ratio of 5:1 is very low. Due to this low compression ratio, a WLA will run on 74 octane gasoline . The WLA also features springer front suspension. Harley-Davidson would not adopt telescopic front forks until after the war. The rear wheel had no suspension, giving this type of motorcycle
1426-428: The BMW engine and drive train and produced the shaft-driven 750 cc 1942 Harley-Davidson XA . This shared no dimensions, no parts or no design concepts (except side valves) with any prior Harley-Davidson engine. Due to the superior cooling of the flat-twin engine with the cylinders across the frame, Harley's XA cylinder heads ran 100 °F (56 °C) cooler than its V-twins. The XA never entered full production:
1488-546: The Davidson family backyard. Most of the major parts, however, were made elsewhere, including some probably fabricated at the West Milwaukee railshops where oldest brother William A. Davidson was toolroom foreman. This prototype machine was functional by September 8, 1904, when it competed in a Milwaukee motorcycle race held at State Fair Park. Edward Hildebrand rode it and placed fourth in the race. In January 1905,
1550-548: The FXST Softail. In response to possible motorcycle market loss due to the aging of baby-boomers, Harley-Davidson bought luxury motorhome manufacturer Holiday Rambler in 1986. In 1996, the company sold Holiday Rambler to the Monaco Coach Corporation . The "Sturgis" model, boasting a dual belt-drive, was introduced initially in 1980 and was made for three years. This bike was then brought back as
1612-484: The Harley-Davidson brand, among them apparel, home décor and ornaments, accessories, toys, scale models of its motorcycles, and video games based on its motorcycle line and the community. In 1901, 20-year-old William S. Harley drew up plans for a small engine with a displacement of 7.07 cubic inches (116 cc) and four-inch (102 mm) flywheels designed for use in a regular pedal-bicycle frame. Over
1674-572: The Italian SWM XN Tornado, which Armstrong acquired the rights to in 1984 when SWM liquidated, and then modified for military use with assistance from CCM . The MT350E mostly saw British and Canadian service, and some are still in use. Harley-Davidson Harley-Davidson, Inc. ( H-D , or simply Harley ) is an American motorcycle manufacturer headquartered in Milwaukee , Wisconsin , United States. Founded in 1903, it
1736-616: The Japanese "big four" manufacturers ( Honda , Kawasaki , Suzuki , and Yamaha ) revolutionized the North American market by introducing what the motoring press would call the Universal Japanese Motorcycle . In comparison, Harley-Davidson's bikes were expensive and inferior in performance, handling, and quality. Sales and quality declined, and the company almost went bankrupt. The "Harley-Davidson" name
1798-539: The Juneau Avenue factory where it stood for many decades as a tribute. In 1906, Harley and the Davidson brothers built their first factory on Chestnut Street (later Juneau Avenue), at the current location of Harley-Davidson's corporate headquarters. The first Juneau Avenue plant was a 40 ft × 60 ft (12 m × 18 m) single-story wooden structure. The company produced about 50 motorcycles that year. In 1907, William S. Harley graduated from
1860-484: The Reagan administration in 1983, giving Harley-Davidson time to implement their new strategies. Revising stagnated product designs was a crucial centerpiece of Harley-Davidson's turnaround strategy. Rather than trying to mimic popular Japanese designs, the new management deliberately exploited the "retro" appeal of Harley motorcycles, building machines that deliberately adopted the look and feel of their earlier bikes and
1922-653: The Super-10, introduced the Topper scooter, and bought fifty percent of Aermacchi 's motorcycle division. Importation of Aermacchi 's 250 cc horizontal single began the following year. The bike bore Harley-Davidson badges and was marketed as the Harley-Davidson Sprint. The engine of the Sprint was increased to 350 cc in 1969 and would remain that size until 1974, when the four-stroke Sprint

1984-706: The UK, South Africa and other allies, as well as filling orders for different models from the Navy and Marine Corps. Unusually, all the WLAs produced after Pearl Harbor , regardless of the actual year, would be given serial numbers indicating 1942 production. Thus, war-time machines would come to be known as 42WLA s. This may have been in recognition of the continued use of the same specification. Most WLCs were produced in 1942 and 1943, and are marked 42WLC or 43WLC . The precise serial number, as well as casting marks, can be used to date
2046-564: The US Army in World War II and resumed civilian production afterwards, producing a range of large V-twin motorcycles that were successful both on racetracks and for private buyers. Harley-Davidson, on the eve of World War II, was already supplying the Army with a military-specific version of its 45 cubic inches (740 cm ) WL line, called the WLA . The A in this case stood for "Army". Upon
2108-513: The VL under the Rikuo name. An 80 cubic inches (1,300 cm ) flathead engine was added to the line in 1935, by which time the single-cylinder motorcycles had been discontinued. In 1936, the 61E and 61EL models with the " Knucklehead " OHV engines were introduced. Valvetrain problems in early Knucklehead engines required a redesign halfway through its first year of production and retrofitting of
2170-515: The WLA in small numbers in 1940, as part of a general military expansion. The later entry of the United States into World War II saw significantly increased production, with some 70,000 being produced during the war (along with spare parts the equivalent of many more). Harley-Davidson would also produce a close WLA variant for the Canadian Army called the WLC and would also supply smaller numbers to
2232-413: The WLA would cease after the war, but would be revived for the Korean War during the years 1949–1952. Most WLAs in western hands after the war would be sold as surplus and "civilianized"; the many motorcycles available at very low cost would lead to the rise of the chopper and other modified motorcycle styles, as well as the surrounding biker culture . Many a young soldier would come home hoping to get
2294-720: The West, many of those WLAs were preserved during the Cold War. Russia and other former Soviet countries are now a major source of WLAs and parts. The WLA is very similar to civilian models, specifically the WL. Among the changes making it a military model: The US Army would use motorcycles for police and escort work, courier duties, and some scouting, as well as limited use to transport radio and radio suppression equipment. Allied motorcycles were almost never used as combat vehicles or for troop mobility, and so were rarely equipped with sidecars as
2356-462: The company placed small advertisements in the Automobile and Cycle Trade Journal offering bare Harley-Davidson engines to the do-it-yourself trade. By April, they were producing complete motorcycles on a very limited basis. That year, Harley-Davidson dealer Carl H. Lang of Chicago sold three bikes from the five built in the Davidson backyard shed. Years later, the company moved the original shed to
2418-471: The company to a group of 13 investors led by Vaughn Beals and Willie G. Davidson for $ 80 million. The new management team improved product quality, introduced new technologies, and adopted just-in-time inventory management. These operational and product improvements were matched with a strategy of seeking tariff protection for large-displacement motorcycles in the face of intense competition with Japanese manufacturers. These protections were granted by
2480-644: The design of a small German motorcycle, the DKW RT 125 , which they adapted, manufactured, and sold from 1948 to 1966. Various models were made, including the Hummer from 1955 to 1959, but they are all colloquially referred to as "Hummers" at present. BSA in the United Kingdom took the same design as the foundation of their BSA Bantam . In 1960, Harley-Davidson consolidated the Model 165 and Hummer lines into
2542-519: The facility to Cagiva , owned by the Castiglioni family. In 1952, following their application to the U.S. Tariff Commission for a 40 percent tax on imported motorcycles, Harley-Davidson was charged with restrictive practices. In 1969, American Machine and Foundry (AMF) bought the company, streamlined production, and slashed the workforce. This tactic resulted in a labor strike and cost-cutting produced lower-quality bikes. Simultaneously,

2604-448: The front cylinder. In 1929, Vivian Bales drove a record 5,000 miles across the United States and Canada on a D-model. The Great Depression began a few months after the introduction of their 45 cu in (740 cm ) model. Harley-Davidson's sales fell from 21,000 in 1929 to 3,703 in 1933. Despite this, Harley-Davidson unveiled a new lineup for 1934, which included a flathead engine and Art Deco styling. In order to survive
2666-642: The military demanded motorcycles for the war effort. Harleys had already been used by the military in the Pancho Villa Expedition but World War I was the first time that it was adopted for military issue, first with the British Model H produced by Triumph Motorcycles Ltd in 1915. The U.S. military purchased over 20,000 motorcycles from Harley-Davidson. Harley-Davidson launched a line of bicycles in 1917 in hopes of recruiting more domestic customers for its motorcycles. Models included
2728-520: The motorcycle by that time had been eclipsed by the Jeep as the Army's general-purpose vehicle, and the WLA ;– already in production – was sufficient for its limited police, escort, and courier roles. Only 1,000 were made and the XA never went into full production. It remains the only shaft-driven Harley-Davidson ever made. As part of war reparations , Harley-Davidson acquired
2790-413: The motorized bicycle category and marked the path to future motorcycle designs. They also received help with their bigger engine from outboard motor pioneer Ole Evinrude , who was then building gas engines of his own design for automotive use on Milwaukee's Lake Street. The prototype of the new loop-frame Harley-Davidson was assembled in a 10 ft × 15 ft (3.0 m × 4.6 m) shed in
2852-466: The name Rikuo. Production continued until 1958. In 1998, the first Harley-Davidson factory outside the US opened in Manaus , Brazil, taking advantage of the free economic zone there. The location was positioned to sell motorcycles in the southern hemisphere market. In August 2009, Harley-Davidson launched Harley-Davidson India and started selling motorcycles there in 2010. The company established
2914-438: The new valvetrain on earlier engines. By 1937, all Harley-Davidson flathead engines were equipped with dry-sump oil recirculation systems similar to the one introduced in the "Knucklehead" OHV engine. The revised 74 cubic inches (1,210 cm ) V and VL models were renamed U and UL, the 80 cu in (1,300 cm ) VH and VLH to be renamed UH and ULH, and the 45 cu in (740 cm ) R to be renamed W. In 1941,

It was finished in 1903 with the help of Arthur's brother Walter Davidson. Upon testing their power-cycle, Harley and the Davidson brothers found it unable to climb the hills around Milwaukee without pedal assistance, and they wrote off their first motor-bicycle as
3038-567: The nickname "hard tail". Harley-Davidson provided motorcycles to the Army during World War I and for earlier excursions against Mexican revolutionaries such as Pancho Villa . During World War II, the Army produced a specification for a motorcycle much like the BMWs used by German forces. That meant shaft drive, a boxer engine , and several other features that made the BMWs exceptionally reliable and low-maintenance machines. Harley-Davidson produced
3100-458: The observation that the motorcycle is somewhat wider than other bikes when viewed head-on. 1993 and 1994 saw the replacement of FXR models with the Dyna (FXD), which became the sole rubber mount FX Big Twin frame in 1994. The FXR was revived briefly from 1999 to 2000 for special limited editions (FXR , FXR & FXR ). Harley-Davidson celebrated their 100th anniversary on September 1, 2003 with
3162-585: The outbreak of war, the company, along with most other manufacturing enterprises, shifted to war work. More than 90,000 military motorcycles, mostly WLAs and WLCs (the Canadian version) were produced, many to be provided to allies. Harley-Davidson received two Army-Navy "E" Awards , one in 1943 and the other in 1945, which were awarded for Excellence in Production. Shipments to the Soviet Union under

In 1911, the company introduced an improved V-Twin model with a displacement of 49.48 cubic inches (811 cc) and mechanically operated intake valves, as opposed to the "automatic" intake valves used on earlier V-Twins that opened by engine vacuum. It
3286-567: The remainder of the Depression, the company manufactured industrial powerplants based on their motorcycle engines. They also designed and built a three-wheeled delivery vehicle called the Servi-Car , which remained in production until 1973. Alfred Rich Child opened a production line in Japan in the mid-1930s with the 74 cu in (1,210 cm ) VL. The Japanese license-holder, Sankyo Seiyaku Corporation, severed its business relations with Harley-Davidson in 1936 and continued manufacturing
3348-462: The subsequent customizations of owners of that era. Many components such as brakes, forks, shocks, carburetors, electrics and wheels were outsourced from foreign manufacturers and quality increased, technical improvements were made, and buyers slowly returned. Harley-Davidson bought the "Sub Shock" cantilever-swingarm rear suspension design from Missouri engineer Bill Davis and developed it into its Softail series of motorcycles, introduced in 1984 with

On September 24, 2020, Harley Davidson announced that it would discontinue its sales and manufacturing operations in India due to weak demand and sales. The move involves $ 75 million in restructuring costs, 70 layoffs and the closure of its Bawal plant in northern India. Octane Octane is a hydrocarbon and an alkane with
3472-544: The traditional diamond frame men's bicycle, a step-through frame 3–18 "Ladies Standard", and a 5–17 "Boy Scout" for youth. The effort was discontinued in 1923 because of disappointing sales. The bicycles were built for Harley-Davidson in Dayton , Ohio by the Davis Machine Company from 1917 to 1921, when Davis stopped manufacturing bicycles. By 1920 Harley-Davidson was the largest motorcycle manufacturer in
3534-425: The world, with 28,189 machines produced and dealers in 67 countries. In 1921, Otto Walker set a record on a Harley-Davidson as the first motorcycle to win a race at an average speed greater than 100 mph (160 km/h). Harley-Davidson put several improvements in place during the 1920s, such as a new 74 cubic inch (1,212.6 cc) V-Twin introduced in 1921, and the "teardrop" gas tank in 1925. They added
3596-412: The yellow brick factory had been demolished and a new five-story structure had been built on the site which took up two blocks along Juneau Avenue and around the corner on 38th Street. Despite the competition, Harley-Davidson was already pulling ahead of Indian and dominated motorcycle racing after 1914. Production that year swelled to 16,284 machines. In 1917, the United States entered World War I and
3658-615: Was common on the German side. The WLAs in Soviet service however were often equipped with sidecars and were used as battle vehicles in the frontlines. Nevertheless, the WLA acquired the nickname "Liberator", since it was seen ridden by soldiers liberating occupied Europe. The engine of the WLA is a side-valve design, which is reliable though not particularly efficient in comparison to overhead-valve designs. Harley-Davidson already had overhead valve engines in production for its Big Twin lines, but
3720-583: Was discontinued. After the Pacer and Scat models were discontinued at the end of 1965, the Bobcat became the last of Harley-Davidson's American-made two-stroke motorcycles. The Bobcat was manufactured only in the 1966 model year. Harley-Davidson replaced their American-made lightweight two-stroke motorcycles with the Italian Aermacchi -built two-stroke powered M-65, M-65S, and Rapido. The M-65 had

In 1977, following the successful manufacture of the Liberty Edition to commemorate America's bicentennial in 1976, Harley-Davidson produced what has become one of its most controversial models, the Harley-Davidson Confederate Edition . The bike was essentially a stock Harley-Davidson with Confederate -specific paint and details. In 1981, AMF sold

In 1912, Harley-Davidson introduced their patented "Ful-Floteing Seat", which was suspended by a coil spring inside the seat tube. The spring tension could be adjusted to suit the rider's weight, and more than 3 inches (76 mm) of travel was available. Harley-Davidson used seats of this type until 1958. By 1913,
