The BMW R75 is a World War II-era motorcycle and sidecar mixture produced by the German company BMW.
Within the 1930s BMW were producing a variety of popular and impressive motorcycles. In 1938 development of the R75 were only available in response to a demand from the German Military.
Preproduction types of the R75 were power with a 750 cc area valve engine, that was predicated on the R71 engine unit. Nonetheless it was quickly found essential to design an all-new OHV 750 cc engine motor for the R75 unit. This OHV engine motor later proved to be the basis for following post-war twin BMW engines like the R51/3, R67 and R68.
The 3rd side-car wheel was motivated with an axle connected to the trunk wheel of the motorcycle. These were fitted with a locking differential and selectable road and off-road items ratios by which all four and invert gears worked well. This made the R75 highly manoeuvrable and with the capacity of negotiating most areas. Additional 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 generally utilized by the Wehrmacht in Russia and North Africa, though over time 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 upon standardization of parts for both machines, with a view of eventually creating 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. In addition they decided that the manufacture 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, manufacturing 20,000 each year.
Since the goal of 20,200 BMW R75's was not reached, it continued to be in production before Eisenach factory was so terribly damaged by Allied bombing that development ceased in 1944. An additional 98 systems were built by the Soviets in 1946 as reparations.
