In 1973, BMW replaced the R 75/5 model with the R 75/6 motorcycle, which featured a large number of innovations, such as disc brakes on the front wheel and new five-speed transmission. The bike was considered a modern and advanced motorcycle at the time.
The 1973 BMW R 75/6 model adopted the maintenance measures introduced in the last year of production of the /5 series, such as the rear wheel swingarm extended by 50 mm that improved the driving stability at high speeds and when used with a passenger and luggage.
At the core of the model was a 745cc air-cooled four-stroke twin-cylinder boxer engine with a power output of 50 hp available at 6,200 rpm. With a curb weight of 210 kg (463 lbs), the bike hit a top speed of 177 kph (109 mph).
For better braking, on the front wheel was mounted a 260 mm single brake disc and a 200 mm simplex drum unit on the rear.
For suspension, the bike packed a telescopic fork with hydraulic shock absorbers on the front wheel and a long swingarm with adjustable shock absorbers on the rear wheel.
The bike came with standard features such as wire-spoke wheels, a dual exhaust system, a center stand, a large headlamp, a dual seat, pillion grab rails, and an analog instrumentation panel.
