An all-new design that was supposed to replace BMW's traditional flat-twins, the BMW K100 arrived for 1984 restating the virtues of solidity, comfort and exemplary build quality long associated with the marque. An 8-valve twin-cam unit displacing 998cc, the brick-like, four-cylinder motor was laid on its side, lowering the center of gravity, and mounted fore-and-aft to facilitate the retention of BMW's characteristic shaft drive. Bosch electronic fuel injection was employed and the long-stroke four developed its maximum output of 90bhp at a relatively low 8,000rpm. In 1985 the K100 spawned a 740cc three-cylinder K75 variant that featured a 120-degree crankshaft and a higher compression ratio. Weighing less than the K100 and with 75bhp on tap, the K75 was a lively performer and deservedly popular, but did not receive the development that went into the four-cylinder models, which would later benefit from four-valves-per-cylinder heads. The usual range of BMW model variants was produced up to the end of three-cylinder K-Series production in 1995.

EngineEdit

The engine was a liquid cooled in-line three, four-stroke. A 67.0mm bore x 70.0mm stroke result in a displacement of just 740.0 cubic centimeters. Fuel was supplied via a double overhead cams/twin cam (dohc).

DriveEdit

The bike has a 5-speed transmission. Power was moderated via the dry, single plate.

ChassisEdit

It came with a 100/90-18 front tire and a 130/90-17 rear tire. Stopping was achieved via dual disc in the front and a single disc in the rear. The front suspension was a telescopic fork with hydraulic shock absorber while the rear was equipped with a Monolever swinging arm. The K75 was fitted with a 5.55 Gallon (21.00 Liters) fuel tank. The bike weighed just 500.45 pounds (227.0 Kg). The wheelbase was 59.69 inches (1516 mm) long.
