The BMW R75 is a global Battle II-era motorcycle and sidecar mixture produced by the German company BMW.
In the 1930s BMW were producing a volume of popular and highly effective motorcycles. In 1938 development of the R75 started in response to a get from the German Military.
Preproduction types of the R75 were driven with a 750 cc aspect valve engine, which was based on the R71 engine. However it was quickly found necessary to design an all-new OHV 750 cc engine motor for the R75 product. This OHV engine later proved to be the foundation for following post-war twin BMW engines like the R51/3, R67 and R68.
The 3rd side-car wheel was influenced with an axle connected to the rear wheel of the motorcycle. We were holding built in with a locking differential and selectable road and off-road items ratios by which all four and change gears performed. This made the R75 highly manoeuvrable and with the capacity of negotiating most surfaces. A few other motorcycle manufactures, like FN and Norton, provided an optional drive to sidecars.
The BMW R75 and its own rival the Z?ndapp KS 750 were both greatly utilized 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 building a Z?ndapp-BMW hybrid (designated the BW 43), in which a BMW 286/1 side-car would be grafted onto a Z?ndapp KS 750 motorcycle. In addition they agreed that the make of the R75 would stop once production reached 20,200 products, and after that point BMW and Z?ndapp would only produce the Z?ndapp-BMW machine, developing 20,000 each year.
Since the target of 20,200 BMW R75's was not reached, it remained in production until the Eisenach manufacturing plant was so badly harmed by Allied bombing that development ceased in 1944. A further 98 units were constructed by the Soviets in 1946 as reparations.
