In 1983, at the Paris Salon, alongside the basic BMW k 100 model, the K 100 RS was present on display as the second member of the K family.
The RS model attracted attention with its half-shell fairings, which in addition to the elegant lines, also had sophisticated aerodynamic qualities.
The driver benefitted from weather protection and was able to 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 windshield.
At the time, the 1983 BMW K 100 RS was a great offer in the large-capacity sports tourer and got a large fan community.
The 987cc four-cylinder in-line engine that powered the RS with an output power of 90 hp at 8,000 rpm and 84 Nm (62 lb-ft) of torque at 8,250 rpm pushed 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 such as 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.
