The '''[[BMW]] K75''' was a | The '''[[BMW]] K75''' was a [[inline three cylinder]], [[four-stroke]] Naked [[motorcycle]] produced by [[BMW]] between 1985 and 1996. It could reach a top speed of 121 mph (194 km/h). Max [[torque]] was 49.2 ft/lbs (66.7 Nm) @ 6750 RPM. Claimed [[horsepower]] was 73.35 HP (54.7 KW) @ 8500 RPM. | ||
An all-new design that was supposed to replace [[BMW]]'s traditional flat-twins, the [[BMW K100|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. | An all-new design that was supposed to replace [[BMW]]'s traditional flat-twins, the [[BMW K100|BMW K100]] arrived for 1984 restating the virtues of solidity, comfort and exemplary build quality long associated with the marque.
