In 1988 BMW designed one of its most extreme motorcycles
Known as K1, it was derived from the K100 and remained in production until 1993
In 1983, BMW Motorrad presented the new K100, a motorcycle designed to comply with the new regulations on harmful emissions and to adequately compare with vehicles produced in Japan.The vehicle had a good commercial success, but the German technicians realized that based on it they could obtain a high-performance sports bike.
A first static prototype was presented at the 1984 Cologne motorcycle show, while the final model was built four years later.Called K1, it was based on the K100 chassis which had been covered with a fiberglass fairing that guaranteed an aerodynamic coefficient of just 0.38 cx.
The design of the propulsion unit was entrusted to the engineers Josef Fritzenwenger and Stefan Pachernegg, who used as a mechanical basis an automobile engine built by Peugeot.The engine was a 987 cc four-cylinder engine capable of delivering the power of 100 hp and pushing the K1 up to the maximum speed of 240 km/h.
The braking system was made by Brembo, while the suspensions consisted of a Marzocchi fork in the front section and a Paralever system with Blistein shock absorber in the rear.Unfortunately the K1 failed to have adequate commercial success due to poor handling and excessive heat emanating from the engine.
