In 1985, alongside the standard K75 model, the German motorcycle maker introduced the BMW K75 S, a sportier version of the RT model. Compared to the base K75 model, the S version packed a sportier fairing and delivered the same technical, visual, and performance specifications.
The BMW K75 debuted in 1985 and was powered by a three-cylinder engine with a balancer shaft and a final shaft drive. The motorcycle was manufactured until 1995 and was available in several variants, like the US-only naked K75 T, the bikini-fired K75 C, the sport-faired K75 S, the naked base model K75, and the fully-faired K75 RT.
Aesthetically, the motorcycle had standard features, such as eight-spoke aluminum alloy wheels, a center stand, a one-piece dual seat with pillion grab rails, a three-into-one exhaust system with a muffler mounted on the left-hand side, a sports fairing with a rectangular headlight, and a windscreen.
In the performance department, the 1985 BMW K75 S had its soul brought to life by a 740cc four-stroke liquid-cooled three-cylinder engine with a fuel injection system handling the pistons, boasting 75 hp at 8,500 rpm and 68 Nm (50 lb-ft) torque at 6,570 rpm.
The bike's engine was coupled to a five-speed manual transmission with a dry single-plate clutch, linked to the rear wheel through a final shaft drive, pushing the machine to a top speed of 210 kph (131 mph).
