The BMW R75 is a global Battle II-era motorcycle and sidecar blend made by the German company BMW.
Inside the 1930s BMW were creating a number of popular and highly effective motorcycles. In 1938 development of the R75 started in response to a request from the German Military.
Preproduction models of the R75 were power by the 750 cc aspect valve engine, which 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 product. This OHV engine later became the basis for succeeding post-war twin BMW engines like the R51/3, R67 and R68.
The 3rd side-car wheel was powered with an axle connected to the trunk wheel of the motorcycle. They were fitted with a locking differential and selectable street and off-road equipment ratios through which all four and change gears worked well. This made the R75 highly manoeuvrable and capable of negotiating most areas. 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 extensively employed by the Wehrmacht in Russia and North Africa, though after a period of analysis it became clear that the Z?ndapp was the superior machine. In August 1942 Z?ndapp and BMW, on the urging of the Military, agreed upon standardization of parts for both machines, with a view of eventually developing a Z?ndapp-BMW hybrid (chosen the BW 43), in which a BMW 286/1 side-car would be grafted onto a Z?ndapp KS 750 motorcycle. In addition they decided that the make of the R75 would cease once production come to 20,200 products, and from then on point BMW and Z?ndapp would only produce the Z?ndapp-BMW machine, processing 20,000 every year.
Since the concentrate on of 20,200 BMW R75's had not been reached, it continued to be in production before Eisenach factory was so badly destroyed by Allied bombing that development ceased in 1944. An additional 98 items were built by the Soviets in 1946 as reparations.
