The BMW R90S is a 900cc sport motorcycle produced by BMW from 1973 to 1976. BMW commissioned designer Hans Muth to oversee the R90S, which became the flagship of the boxer engined "/6" range. Sporting distinctive two-tone paintwork, a bikini fairing and a new tail, the R90S was intended to shrug off the enduring image of BMW bikes as staid and utilitarian.
The 67 bhp (50 kW) R90S had a top speed of 124 mph (200 km/h),[3] it ran the quarter mile in around 13.5 seconds and it accelerated from 0 to 62 mph (0–100 km/h) in 4.8 seconds.[3] Maximum torque was delivered at 5,500 rpm and the engine redlined at 7,200 rpm.
