BMW R 45 (1977-1978) Specs, Performance & Photos

In 1985, the German motorcycle manufacturer released the BMW R 45, a motorcycle in its eighth and final year of production. The bike was manufactured for eight years, from 1978 to 1985. Until it was revised in 1980, the maker produced over 15,900 units, and by the time it ended production in 1985, more than 28,150 units were produced.

The BMW R 45 was a mid-range motorcycle produced by BMW from 1978 to 1985. It was powered by a twin-cylinder boxer engine assisted by a five-speed transmission and a shaft final drive.

The bike was available in two versions, one with 27 hp and the other with 35 hp, with a claimed top speed of 160 kph (99 mph). In 1979, the 27-hp model was the best-selling motorcycle in Germany.

The 1985 model came in the same shape and form as the previous one, delivering the same technical, visual, and performance specifications without any significant modifications whatsoever.

In the aesthetic department, the motorcycle packed standard fittings, such as a front fender mounted close to the wheel, a round headlight, a one-piece dual seat, side-mounted rear shocks, a two-into-two exhaust system with a silencer mounted on each side, a center stand, and multi-spoke aluminum wheels.

As for the power figures, the 1985 BMW R 45 had its soul brought to life by a 453cc four-stroke air-cooled twin-cylinder boxer engine with two Bing carburetors in charge, boasting 27 hp at 6,500 rpm and 38 Nm (28 lb-ft) torque at 5,500 rpm.
