Segment: Naked / Road
Production years: 1990, 1991
In 1991, in addition to the successful revision of the Paralever GS models, BMW prepared a surprise for boxer fans and tried to reproduce the success on a street version motorcycle. The 1991 BMW R 100 R received a naked bike look with classic style elements.
The bike featured cross-spoked rims, a two-in-one exhaust system with chrome-plated rear mufflers, a 200 mm round chrome-plated headlight, and handlebar fittings originated from the K series.
The bike's trust came from the 980cc flat-twin engine with a power output of 60 hp at 6,500 rpm and 76 Nm (56 lb-ft) of torque with a peak at 6,500 rpm. The engine power, combined with a five-speed manual transmission and a 218 kg (481 lbs) curb weight, managed to send the bike to a top speed of 181 kph (115 mph).
The up-to-date braking technology consisted of a 285 mm floating disc brake from the GS with a four-piston caliper which originated from the BMW K series (optional 285 mm double disc) on the front wheel and a 200 mm drum braking unit on the rear wheel.
For suspension, the model packed a telescopic fork with hydraulic shock absorbers on the front and a BMW Paralever single-sided swingarm with a central spring strut on the rear.
