The BMW R 80 G/S was a dual-sports motorcycle produced by BMW in Berlin, Germany, from 1980 to 1987. Over its production time, the maker manufactured over 21,800 motorcycles. The bike's G/S designations represent the German words Gelande/Strasse, which translates to off-road/road.
In addition, the R 80 G/S was the first motorcycle in BMW's G/S range of dual-sports motorcycles, which comprised over 500,000 produced units. Also, the motorcycle was often considered the world's first "Adventure Bike" capable of tackling both on and off-road conditions.
In 1985, the German motorcycle manufacturer launched the BMW R 80 G/S, a dual-sports motorcycle in its sixth consecutive production year that featured the same package. Over its production time, the bike remained largely unchanged, offering the same specifications without significant changes.
In the aesthetic department, the motorcycle had standard fittings, a round headlight placed into a small cowl, a one-piece dual seat with passenger grab rails, a small luggage rack, a center stand, a high-mounted front fender, and wire-spoke wheels.
As for the power figures, the 1985 BMW R 80 G/S boasted 50 hp with maximum strength at 6,500 rpm and 57 Nm (42 lb-ft) torque at 5,000 rpm from a 797cc four-stroke air-cooled twin-cylinder boxer engine fed by two Bing carburetors.
The power generated by the engine was transferred to a five-speed transmission and sent to the rear end via a final shaft drive, pushing the motorcycle to a top speed of 167 kph (104 mph).
