In 1973, BMW launched the revised /6 series that marketed two models in the 900cc class. One was the R 90 S, a sports model, and the other was the R 90/6, a high-torque tourer that appealed to enthusiasts of long-distance trips.
The R 90/6 model was the first motorcycle in the world equipped with H4 light as standard, which in conjunction with the large 200 mm round headlight, resulted in excellent light output. The 1973 BMW R 90/6 featured more success shown by the sales numbers, which were around 3,600 units more than the sportier model.
The R 90/6 motorcycle had at its core an 898cc air-cooled, four-stroke, two-cylinder boxer engine that provided an output power of 60 hp at 6,500 rpm and a maximum top speed of 188 kph (115 mph).
For suspension, the bike had a telescopic fork with hydraulic shock absorbers on the front wheel and a long swingarm with adjustable shock absorbers on the rear wheel.
For braking purposes, the model featured a 260 mm disc on the front and a 200 mm simplex drum unit on the rear.
In addition, the bike came with standard features such as a dual seat with pillion grab rails, a large round headlight, wire-spoked wheels, a dual exhaust system, and an analog instrument cluster.
