The BMW K100 RS was a sports-touring motorcycle based on the standard K100 model. The RS debuted in 1983 and addressed riders searching for a dependable, stable machine with enhanced performance.
In 1985, the German motorcycle manufacturer released the BMW K100 RS, a motorcycle in its third consecutive production year. It delivered the same technical, visual, and performance specifications as previous models without any modifications.
In addition to the base and RS models, the German maker offered several variations, such as the K100 C with a small cockpit fairing mounted on the handlebar, the K100 RT with a full touring fairing, the K100 LT with a taller windscreen and luxury touring equipment, and K100 TIC designed for Police, Military, Fire, and Ambulance departments.
The bike was fitted with standard features, such as a half fairing with an integrated square headlight, a medium-sized windscreen, a one-piece dual seat with passenger handles, a luggage rack, a four-into-one exhaust system with a silencer mounted on the left-hand side, and eight-spoke aluminum alloy wheels.
In terms of power, the 1985 BMW K100 RS was equipped with a 987cc four-stroke liquid-cooled four-cylinder engine assisted by a fuel injection system, boasting 90 hp at 8,000 rpm and 84 Nm (62 lb-ft) torque at 8,250 rpm.
The big machine was set in motion by a five-speed transmission with a cable-operated clutch that sent the power to the rear wheel via a final shaft drive, spinning the wheel to a top speed of 220 kph (136 mph).
