Segment: Naked / Road
Production years: 1981, 1982
The BMW R 80 ST was the road-oriented sister of the BMW R 80 G/S travel enduro. It was manufactured from 1982 until 1984 and featured several adjustments to be used on the road, like a 19-inch front wheel, road tires, and a shorter suspension travel, significantly increasing ground clearance.
In 1984, the German motorcycle maker released the BMW R 80 ST, a road motorcycle in its third and last year of production. It didn't have a direct successor but was later followed by the BMW R 80 Monolever and BMW R 100 R with a Paralever system.
The 1984 motorcycle came with the same package as the previous model, featuring the same technical, visual, and performance specifications without any modifications whatsoever.
Visually, the motorcycle had standard fittings, like a round headlight on the front, a one-piece dual seat, a passenger grab handle, a side stand, a single-sided swingarm, and wire-spoke wheels with road tires.
As for the power figures, the 1984 BMW R 80 ST was powered by a 797cc four-stroke air-cooled twin-cylinder boxer engine mounted at its core that delivered an output power of 50 hp at 6,500 rpm and 58 Nm (43 lb-ft) torque at 5,000 rpm.
The engine was married to a five-speed transmission that transmitted the power from the engine to the rear end via a final shaft drive, pushing the motorcycle to a top speed of 171 kph (106 mph).
