The BMW R75 is a World War II-era motorcycle and sidecar blend produced by the German company BMW.
Within the 1930s BMW were creating a range of popular and highly effective motorcycles. In 1938 development of the R75 were only available in respond to a demand from the German Army.
Preproduction types of the R75 were powered by way of a 750 cc area valve engine, that was based on the R71 engine unit. Nonetheless it was quickly found essential to design an all-new OHV 750 cc engine unit for the R75 product. This OHV engine unit later became the foundation for following post-war twin BMW engines like the R51/3, R67 and R68.
The 3rd side-car wheel was powered with an axle linked to the trunk wheel of the motorcycle. We were holding fixed with a locking differential and selectable road and off-road items ratios by which all and change gears did the trick. This made the R75 highly manoeuvrable and with the capacity of negotiating most floors. A few other motorcycle manufactures, like FN and Norton, provided an optional drive to sidecars.
The BMW R75 and its own competitor the Z?ndapp KS 750 were both broadly employed by the Wehrmacht in Russia and North Africa, though after a period of evaluation it became clear that the Z?ndapp was the superior machine. In August 1942 Z?ndapp and BMW, on the urging of the Army, agreed after standardization of parts for both machines, with a view of eventually developing a Z?ndapp-BMW hybrid (selected the BW 43), when a BMW 286/1 side-car would be grafted onto a Z?ndapp KS 750 motorcycle. They also decided that the production of the R75 would stop once production come to 20,200 models, and after that point BMW and Z?ndapp would only produce the Z?ndapp-BMW machine, making 20,000 every year.
Since the concentrate on of 20,200 BMW R75's was not reached, it continued to be in production before Eisenach manufacturing plant was so badly damaged by Allied bombing that development ceased in 1944. A further 98 models were constructed by the Soviets in 1946 as reparations.
