34-625: Before the introduction of the 2009 models the series consisted of four main models; the XJ600S, XJ600N, XJ900S and XJ900GT and the lesser known YBR125 Diversion. The XJ600S is known as the Diversion in most parts of the world but as the Seca II in the North American and Australian markets. The bike has a small top fairing although a lower fairing is available as an accessory. The XJ600S

68-583: A shaft drive while the 600cc models are chain driven . The XJ900S/GT is known as Diversion 900 on the European market. In the United States the bike appeared as the 1983 Seca XJ900RK. The Yamaha Diversion has been used as a police motorcycle all over the world. Such models are built by Yamaha to the specifications of individual police departments. Generally the XJ900S is chosen for police use but

102-458: A front fairing, a rear fairing, a belly fairing, or any combination of these. Alternatively, a single fairing may partially or fully enclose the entire motorcycle, and may even enclose the rider. The importance of streamlining was known very early in the 20th century, and some streamlining was seen on racing motorcycles as early as the 1920s. Although motorcycles generally have a much higher power-to-weight ratio than cars, bikes – and particularly

136-699: A great deal of low-end horsepower , and a more relaxed, upright seating position than sport bikes . Particularly in the US, touring motorcycles may be given names such as bagger , full bagger , full dresser , full dress tourer , or dresser . These monikers (often used disparagingly or jocularly) originally applied to cruisers with full sets of saddlebags or panniers such as Harley-Davidsons ; but these terms may now refer to any touring motorcycle. Full-dress touring motorcycles are generally characterized by extremely large fairings and ample bodywork compared to other types of tourers. Hard luggage, e.g. panniers and

170-536: A long time, probably due to its low price, modest fuel consumption, longevity and reliability. The XJ600N is almost identical to the XJ600S except that it is a naked bike and the instrument panel is different, as it turns with the handlebars . This model was not sold in North America. The XJ900 is a descendant of the earlier XJ900 model. The XJ900S and the XJ900GT are both the same basic motorcycle except

204-621: A naked motorcycle. The fully faired FZ6R is the American equivalent to the European XJ6 Diversion F model with the exception of not having the ABS and electronic immobilizer. The engine is a detuned Fazer engine and both versions are offered with optional ABS braking. The new line has upgraded to a liquid-cooled 16 valve 4-stroke forward-inclined parallel 4-cylinder engine developing 78 horsepower (57 kW) / 59.7 Nm. Yamaha has kept

238-429: A tail unit or race tail, is mounted behind the seat and rider. Some also extend to the sides of, and below, the saddle and usually providing a small storage space. Particularly on sports/ race replica style bikes with dual seats, detachable colour matched Tail Humps are also available which either cover the passenger seat or are exchanged for it, blending in with the tail unit and side panels they give extra streamlining and

272-724: A top box, are integrated into the design of the motorcycle which usually has a very large displacement, torquey engine with a very upright, comfortable riding position. Additionally, optional amenities for full-dress tourers might include equipment not normally offered on other motorcycles such as complete stereos (AM/FM radios with CD players or MP3 connections), satellite radio, heated seats and hand-grips, GPS navigation systems, custom windshields, integrated air compressors, and air bags. Beyond what manufacturers supply, 'full dressers' are often customized by owners with additional accessories. Full-dress tourers are designed specifically for riding on pavement. A few examples of full-dress tourers are

306-438: A touring fairing protect the upright rider from the worst of this, and the windscreen is functional. Full fairings can also provide protection to the engine and chassis in the event of a crash where the fairings, rather than the engine covers and/or frame, slide on the road. Half fairings usually feature a windscreen and extend below the handlebars, possibly as far down as the sides of the cylinder block, but generally do not cover

340-493: Is a descendant of the XJ600 models manufactured between 1984 and 1991. It is fitted with a 598cc, air-cooled 8-valve inline-four engine producing 61 hp (45 kW) and 55 N⋅m (41 lbf⋅ft). The engine from the original XJ600 model was tuned towards improved low- and midrange power, sacrificing some peak power. 600cc Diversion models were manufactured from 1992 to 2004. US Seca IIs were manufactured from 1992 to 1998. As

374-426: Is a type of motorcycle designed for touring . Although almost any motorcycle can be used for this purpose, manufacturers have developed specific models designed to address the particular needs of these riders. Touring motorcycles commonly have large displacement fairings and windshields that offer a high degree of weather and wind protection, large-capacity fuel tanks for long ranges between fill-ups, engines with

408-438: Is lighter, and more durable than ABS Plastic. Damaged fiberglass can be repaired by applying new layers of woven fiberglass cloth mixed with a polymer such as epoxy over the damaged area, followed by sanding and finishing. Carbon-fiber-reinforced polymer is the lightest, but most expensive, fairing material. It is used on the most extreme sport and racing motorcycle fairings. Touring motorcycle A touring motorcycle

442-522: Is like an expanded and extended nacelle. It is attached only to the forks or yokes, encompassing the headlight and instruments, and varying portions of the handlebars, and moves with them as the bars are turned. Quarter and half fairings are often paired with a belly pan below the engine for diverting air flow away from under the engine to reduce aerodynamic lift , as well as cosmetic reasons. Some track day or racing rules require belly pans to catch leaked fluids. A tail fairing, sometimes referred to as

476-480: The GT , typically for touring motorcycles, has a large fairing and two Krauser K2 panniers while the XJ900S has a small top fairing like the XJ600S. On the dashboard (wider than that of the 600cc models) there are some extra gauges such as a fuel gauge . It is a sports/touring machine fitted with an 892cc, air-cooled 8-valve inline-four engine with 89 hp (66 kW) and 85 N⋅m (63 lbf⋅ft). The XJ900S/GT has

510-717: The Yamaha Royal Star Venture , the Honda Gold Wing , and Harley-Davidson Electra Glide . A recent type, the adventure touring motorcycle is a dual-sport motorcycle that allows long-range touring both on-road and off-road capabilities. Adventure tourers have high ground clearance (for off-road purposes), large fuel capacity, and under-stressed engines for high reliability. They may have rugged GPS navigation systems, wire-spoked wheels with road-legal knobby tyres (high end models may have tubeless tyres to increase high speed safety), skid plates (to protect

544-413: The triple clamp . Also called a café fairing or bikini fairing, it stops well below the level of the rider's head, relying primarily on air deflection to protect the rider's head and chest from the slipstream. A Handlebar fairing, also called headlight fairing or headlamp fairing, is not fixed to the main chassis as with other types of fairings, which do not move. A handlebar fairing complete with screen

578-560: The Dakar Rally did so on a Yamaha XT500 . Sport tourers are a hybrid form of motorcycle of the sport bike and tourer. Forming a niche market, sport tourers combine the performance of a sport bike with the long-distance capabilities and comfort of a touring motorcycle. They exhibit much greater emphasis on sporting performance (in both handling and speed) than conventional tourers. Although Honda has three sport touring models, and BMW has four, most motorcycle manufacturers tend to have

612-521: The Diversion/Seca II design is based on an earlier, well-matured model, changes made to the bike during these years were rather subtle, mostly concerning improvements in fairing: a second front-brake disc and small oil cooler appeared on the 1996 model along with improvements to the carburettors. The Diversion favours an upright riding position more than most 600cc sport bikes, making it usable for commuting . It remained in production for quite

646-521: The XJ600S has also been used. Police specification Diversions are commonly referred to as XJ900P (P for Police) although Yamaha refers to them by their usual model designation (XJ900S or XJ600S) as they do not constitute a separate model. In 2009 Yamaha re-launched the Diversion line in the form of the XJ6 Diversion, XJ6 N and XJ6 Diversion F. The former has a half-fairing while the N version is

680-419: The balance of a motorcycle, inducing wobble. Originally the fairings were cowlings put around the front of the bike, increasing its frontal area. Gradually they became an integral part of the design. Modern fairings increase the frontal area at most by 5% compared to a naked machine. Fairings may carry headlights, instruments, and other items. If the fairing is mounted on the frame, placing other equipment on

714-455: The best possible drag coefficient ratio. Acrylonitrile butadiene styrene (ABS) plastic is commonly used in original equipment sport bikes and certain aftermarket fairing manufacturers due to its strong, flexible and light weight properties. The advantage of ABS over other plastics is that it combines the strength and rigidity of acrylonitrile and styrene with the toughness of polybutadiene rubber. The proportions of each property vary based on

748-581: The engine and transmission during off-road use), and tough metal panniers. Modified adventure tourers are sometimes used in gruelling rally events, such as the Dakar Rally . Adventure tourer models include the BMW R1200GS , the KTM 990 Adventure series, Suzuki V-Strom 1000 , and many others. Although most modern adventure tourers are large capacity bikes, that has not always been so: the first rider to win

782-452: The engine displacement at 600cc for the new Diversion line. The YBR125 Diversion was also available in France around 2005 XJ600N/S Motorcycle fairing A motorcycle fairing is a shell placed over the frame of a motorcycle , especially racing motorcycles and sport bikes , to deflect wind and reduce air drag . The secondary functions are the protection of

816-404: The fairing reduces the weight and rotational inertia of the steering assembly, improving the handling. The BMW R100RS , produced from 1976 to 1984, was the first mass-market sport touring motorcycle to be offered with a full fairing as standard, and marked the beginning of wider adoption of fairings on sports and touring types of motorcycles. The integrated design included a development of

850-466: The frame-mounted tail fairing at the rear of the removable dual seat accessing a storage compartment used on the BMW R90S from 1973, also being the first example of a factory-fitted head (or nose) fairing. A single piece, streamlined shell covering the front half of a motorcycle resembling the nose of an aircraft, sometimes referred to as torpedo fairing. It dramatically reduced the frontal drag, but it

884-478: The look of a single seater racing bike Kawasaki became the first manufacturer to incorporate a tail fairing on a mass production motorcycle when tail units were fitted to the 1972 250cc S1 Mach I , 350cc S2 Mach II , and 750cc H2 Mach IV models. A streamliner motorcycle , such as the NSU Delphin III , uses a fairing which completely encloses both the entire motorcycle and the rider to provide

918-436: The lower half of the motorcycle exposed. The fairing on a race or sport bike is meant as an aerodynamic aid, so the windscreen is rarely looked through. If the rider is sitting up at speed he will be buffeted by his rapid progress through the air and act as a parachute, slowing the bike, while if the rider lies flat on the tank behind the windscreen he generates much less aerodynamic drag. The high windscreen and handlebar width of

952-470: The rider from airborne hazards and wind-induced hypothermia and of the engine components in the case of an accident. A motorcycle windshield will usually be integrated into the design of the fairing. The major benefit of a fairing on sport touring and touring motorcycles is a reduction in aerodynamic drag, which allows for reduced fuel consumption and permits higher speeds at lower engine rpm, which in turn increases engine life. A motorcycle may have

986-511: The rider – are much less streamlined and the effects of aerodynamic drag on motorcycles are very significant. Consequently, any reduction in a motorcycle's drag coefficient pays dividends in improved performance. The term fairing came into use in aircraft aerodynamics with regard to smoothing airflow over a juncture of components where airflow was disrupted. Early streamlining was often unsuccessful resulting in instability. Handlebar fairings, such as those on Harley-Davidson Tourers, sometimes upset

1020-415: The rider's arms and legs to be visible from the side. However, Peter Williams was permitted to give his 1973/74 JPS Norton a Peel -type fairing incorporating handlebar blisters which helped to reduce the drag coefficient to 0.39. This was called so because, in early models, the front wheel mudguard streamlined with the rising windshield part of the fairing resembled the river dolphin 's snout from

1054-447: The side view. Further developments on this design became the norm after dustbin fairings were banned. A full fairing is a large front-mounted fairing, and should not be confused with cabin motorcycle or streamliner motorcycle fairings which fully or partially enclose the entire motorcycle. Full fairings cover both upper and lower portions of the motorcycle, as distinct from a half fairing, which only has an upper section, and leaves

1088-412: The sides of the crankcase or gearbox. Aftermarket kits – 'lowers' – are available to extend some half fairings into full fairings. Due to the popularity of these kits, some motorcycle manufacturers have started to supply their own full fairing conversion kits and even offer their half faired models new with a full factory-fitted kit. A windscreen and minimal fairing extending around the headlamp fixed to

1122-436: The targeted result. There are two common methods of producing an ABS plastic fairing: injection and compression molding. Fiberglass is made of woven fibers, and is used as a reinforcing agent for many polymer products. The composite properly known as glass-reinforced plastic (GRP), is normally referred to by the name of its reinforcing material. Fiberglass fairings are commonly used on the race track. In most cases fiberglass

1156-403: Was banned by Fédération Internationale de Motocyclisme (FIM) from racing in 1958, because it was thought that the frontal point of wind pressure made them highly unstable even with small amounts of yaw . Other reasons cited for the ban were to ensure adequate steering range ( lock-to-lock ) and stability in crosswinds . FIM regulations forbid streamlining beyond the wheel spindles and require
