BMW Motorrad introduced the K1 in 1988 at the Cologne Fair. In 1993 K1 production ended. 6921 pieces were produced.
The bike spins from zero to a hundred in 3.9 seconds and speeds 230 kilometers per hour. It was equipped with an unusual, four cylinder engine with a capacity of 987 ccm. The engine was located on the side, in line with the frame of the motorcycle, with the crankshaft on the right side of the motorcycle, with cylinders, pistons, camshafts, injectors and spark plugs on the left. This system keeps the center of gravity relatively low.
The power supply corresponds to the Bosch electronic injection. Electronic engine control, including the fuel mix, injection and start-up of the motorcycle. It was a novelty in the motorcycle market.
Design was very important. Its task was to achieve the lowest possible air resistance coefficient. The CX ratio is 0.33, the lowest of the then-produced motorcycles. Massive fender is designed to direct the airflow to the fairing and possibly isolate the wheel from swirling. The three holes serve to eliminate the negative pressure produced by the rotating wheel. Direction indicators integrated into the motorcycle. The place of the motorcyclist is very low so he can hide in a motorcycle.
The chassis consists of the front telescopic fork from Marzocchi, while the rear suspension of the Paralever is working on the back.
K1 was one of the first representatives of the hyperbike, and was also the first machine to use so much aerodynamics. The era of these motorcycles ended with the debut of Hayabusa.
