In 1984, the German motorcycle maker released the BMW R 80 G/S, a dual-purpose motorcycle, in its fifth consecutive production year. Like the previous one, the 1984 model packed the same specifications without any changes.

The BMW R 80 G/S was a dual-sports bike produced by BMW in Berlin, Germany, from 1980 to 1987. Over its production period, 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.

The R 80 G/S was the first motorcycle in BMW's G/S family of dual-sports motorcycles, which comprised over 500,000 produced units. In addition, the motorcycle was often considered the world's first "Adventure Bike" capable of tackling both on and off-road conditions.

The bike's visual department was characterized by standard features, such as 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.

It was made around a double-loop tubular steel frame with a bolt-on rear section that comprised a hydraulic telescopic fork with 200 mm travel on the front and a monolever swingarm on the rear with 170 mm of travel.

As for power, the 1984 BMW R 80 G/S was set in motion by a 797cc four-stroke air-cooled twin-cylinder boxer engine mounted underneath its fuel tank, delivering an output power of 50 hp with maximum strength at 6,500 rpm and 57 Nm (42 lb-ft) torque at 5,000 rpm.
