Trophy Winner Comes with Clymers Shop Manual I am listing this for a friend. ***** *********** If you want to know anything more.. feel free to Call Mark 239-848-0406 Thanks The BMW R90S is a sport motorcycle that was produced by BMW between 1973 and 1976. The R90S is considered by many to be one of the first superbikes, and the first such motorcycle from BMW. The first United States AMA Superbike Championship was won in 1976 by British rider Reg Pridmore on a R90S. RARE Only 6,314 Produced Technicle Data The first series of R90S sported a distinctive two tone paintwork (Black/Smoke) called "TT silberrauch" or "TT smoke silver" with adhesive gold pinstripes. Later variants (August 1974 on) were sold both in "Smoke Silver TT" and "Daytona orange" (orange/silver with red pinstriping). The R90S was an individual factory motorcycle – no two left the factory the same due to the individual differences in each motorcycle's paint job, making restoration a subjective task. The R90S sported a small but effective factory-fitted Bikini Fairing, which held four dial instruments (speedometer, tachometer, clock and voltmeter). The bike also possessed an adjustable hydraulic steering damper activated via a knob located on the steering head. Suspension is by telescopic forks at the front and twin shocks at the rear. The rear dampers were adjustable for preload, which is the only suspension adjustment available. Aftermarket fork gaitors are often fitted to the bike but are not required due to the relative hardness of the fork stanchions. Other critical engine differences are that the R90S came equipped with standard 38 mm Dell Orto 'pumper' Carburetors, differing from the previous 26 mm Bing slide carbs or 32 mm Bing CV carbs of the standard "/6" and "/7" 800 cc and 1000 cc series machines. Appearance The bike's visual design was overseen by Hans Muth, who was asked by BMW to create a machine with a unique presence far removed from the staid image offered by previous BMW offerings such as the R69S. This designer later went on to design the R65LS, and also the Suzuki Katana. The R90S possessed a redesigned seat, with a small, styled ducktail, which added a second underseat storage space to add to the original underseat tool tray suitable for lightweight waterproofs, maps, or gloves. Performance On the road, the R90S was a capable solo or two-up sports machine. The addition of either Krauser or BMW hard panniers and either a rear rack or over the cylinder 'toaster racks' made the bike a capable tourer. Overall, the bike can exceed over on a tank of fuel. Its performance is modest compared with modern K-series BMW bikes producing more than , but the pushrod-twin engined bike ran the quarter mile in around 13.5 seconds and went from in just over 5.4 seconds. The R90S came standard with a full toolkit, a hand pump, a first-aid kit and even a small hand towel with an embroidered BMW logo. Owner maintenance is standard practice with these machines. Valve gear was adjusted by simple locknut, and timing was taken care of by points (later replaced by electronic ignition in many models). Most other maintenance tasks were easily achieved due to easy access to most mechanicals. Maximum torque is delivered at about 5500 rpm and redline is at 7200 rpm. Top speed is upright and on the tank. The bike will run at 190 km/h all day if required, but the relative fragility of the overhead valve gear is something that needs to be considered when running the bike over the redline, as it has no rev limiter as found on modern bikes. As the OHV engine pushrod valvegear components were designed ‘off centre’ by four degrees to accommodate future plans to expand the R series bikes to 1000 cc, this slight offset produces additional tensions on the OHV gear at maximum revs that need to be considered by owners who ride over the limit. As for brakes, two 230 mm drilled discs were gripped by single ATE callipers, with a 200 mm drum on the back wheel. The 1974 onwards model bikes make a distinctive noise under braking thanks to the drilled discs. Overall braking performance bettered the Japanese offerings of the time (especially in the wet), but were substandard to contemporary Brembo systems (which were subsequently fitted to BMWs from the "/7" series onwards). The front brake's cable activation system for all BMW "/6" series bikes, including the R90s, is also different to other brands, as the master cylinder is located on the top tube of the frame and is activated by a cable from the lever to the cylinder. The argument was that this system offered greater protection for the master cylinder in the event of a crash. Later "/7" machines reverted to handlebar mounted Brembo master cylinders, with disc brakes replacing rear drums until the advent of the R100R Mystic models in the 1990s. Other features The bike was originally equipped with a phenolic disc and spring engine crankcase breather, which was superseded by a reed valve design on the "/7" series. An original R90S (as with many "/5" and "/6" machines so fitted) makes a 'plopping' noise at idle as the crankcase breather manually opens and closes: later reed type breathers retrofitted to earlier bikes removed this feature. A H4 headlight providing adequate illumination for legal speed touring at night. The switchgear was upgraded in 1975 from the previous "/5" system. The indicator switch now operated on the vertical plane, rather than the horizontal one used by most other manufacturers. , both BMW and Harleys continue with different switchgear to manufacturers in this regard. The ignition key is placed on the left headlight mounting point. The steering lock is mounted in the steering headstock. The tires are narrow in comparison to modern bikes. The 19 inch front and 18 inch rear combination are narrow, but adequate for most riding activities. One advantage of such a narrow tire combination is good stability on dirt roads: Legacy Two R90S bikes placed first and second at the very first AMA Superbike race at Daytona in 1976. On the first place bike was Steve McLauglin and on the second was Reggie Pridmore. The first place bike is now in the BMW Mobil Tradition Collection.
