This R90S is fitted with a type 247 engine, an OHV, two valve per cylinder, air cooled flat-twin engine. The R90S weighs 470 lb and has a five speed all-indirect gearbox connected to a shaft final drive. The model is an extension of the previous 750 cc series "/5" machines. The R90S was one of two 900 cc models introduced in 1974; the other being the 900 cc version of the existing R75/6 machine, the R90/6. There were three series of R90S ('74, '75, and '76). Model year 1974 was September 1973 to August 1974 consisting of 6,058 units produced. The first series of R90S sported a distinctive two tone paintwork (Black/Smoke) called "TT silberrauch" or "TT smoke silver" with adhesive gold pinstripes (no longer hand painted by the factory; only the first series of R90S had these kind of pinstripes. Customer complaints convinced BMW to turn back to hand painted pinstripes for later years). Later variants (August 1974 on) were sold both in "Smoke Silver TT" and "Daytona orange" (orange/silver with red pinstriping). The first series also had aluminum turn signals among other small differences. 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. Look at two identical machines from the same production run and you can see this difference today, which makes restoration a subjective task. On the road, the R90S is 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 236 miles on a tank of fuel. Performance? As the ad said "Not a drag bike...But...we did set 2 National Records!!!!" On Nov. 9, 1975 at Irwindale Raceway during the 3rd Hot Bike Nationals a stock R90S ran an 11.64 E.T. at 118.11 mph.Image 1 • Image 2
