BMW K1 (1987-1988) Specs, Performance & Photos

In 1988, at the IFMA Show, BMW launched the K1 motorcycle, which caused a controversial discussion in motorcyclist circles about the sophisticated aerodynamically body concept down to the last detail, which started from the almost completely covered front wheel to the rear end with a passenger seat cover.

The reinforced frame that came from the K 100 model featured a stiffer Marzocchi fork on the front wheel, a Paralever swingarm on the rear wheel, and a four-piston Brembo brake system with 305 mm floating discs, all that to ensure a stable and safe straight-line at high speeds.

To ensure the required 100 hp output, BMW developed the first four-valve cylinder head in the history of BMW Motorrad for the four-cylinder engine. For the first time in the construction of a series motorcycle, the 1988 BMW K1 combined digital ignition and injection electronics.

Combined with the 987cc in-line four-cylinder engine resulted in a power output of 100 hp with a peak at 8,000 rpm and 100 Nm (74 lb-ft) of torque available at 6,750 rpm that launched the motorcycle to a top speed of 240 kph (150 mph).

The model featured standard equipment such as cast-aluminum wheels, a full fairing, a dual seat, passenger grab rails, a side stand, and a front fender that encloses almost half of the wheel, decreasing wind drag.
