BMW K75 S (1990-1991) Specs, Performance & Photos

The BMW K75 S was a naked motorcycle manufactured by the German Company in 1985. It was derived from the standard K75 model, featuring the same specifications but fitted with a sports fairing and a rectangular headlight.

In 1990, the German bike maker released the BMW K75 S, a more sporty version of the base model. It was in its sixth consecutive production year and came with the same specifications as the previous model without any changes.

The bike boasted standard features in the visual department, including three-spoke lightweight aluminum alloy wheels, a three-into-one exhaust system, a two-up seat with passenger grab handles, a sports fairing with a square headlight, and a medium-sized windscreen.

It packed the same suspension system as other K75 models, comprised of a telescopic fork on the front that provided 185 mm of travel and an aluminum swingarm with a right-hand side-mounted shock absorber with 114 mm of travel.

In terms of power, the 1990 BMW K75 S had its soul brought to life by a 740cc four-stroke liquid-cooled three-cylinder engine mounted underneath its fuel tank, delivering an output power of 75 hp at 8,500 rpm and 68 Nm (50 lb-ft) torque at 6,570 rpm.

All the power generated by the engine was transmitted to a five-speed gearbox controlled by a dry single-plate clutch. The motorcycle reached a top speed of 210 kph (131 mph) via a final shaft drive linked to the transmission.
