In 1983, at the Paris Salon, alongside the standard BMW K100 model, the K100 RS was on display as the second member of the K family.
The K100 RS model attracted attention with its half-shell fairings, which, in addition to the elegant lines, also had sophisticated aerodynamic qualities. At the time, the 1983 BMW K 100 RS was a great offer in the large-capacity sports tourer market and attracted a large fan community.
The driver benefitted from weather protection and could run long distances at average high speeds due to the lower and narrower handlebar than the basic model and the adjustable spoiler installed on the upper edge of the windscreen.
The 987cc in-line four-cylinder engine that powered the 1983 BMW K100 RS with an output power of 90 hp at 8,000 rpm and 84 Nm (62 lb-ft) of torque at 8,250 rpm launched the 249 kg (549 lbs) motorcycle to a top speed of 220 kph (137 mph).
For suspension, the model packed a telescopic fork with a hydraulic damper on the front and a BMW Manolever swingarm with a central spring strut on the rear.
The model came with standard equipment like a small windscreen, a dual seat, a blacked-out exhaust system, a center stand, an analog instrument cluster, cast-aluminum wheels, passenger grab handles, and Brembo brakes with dual front discs and single disc on the rear.
