The BMW R75 is a global Conflict II-era motorcycle and sidecar combo made by the German company BMW.
Inside the 1930s BMW were creating a variety of popular and highly effective motorcycles. In 1938 development of the R75 started in response to a submission from the German Army.
Preproduction types of the R75 were power by a 750 cc part valve engine, that was predicated 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 motor later became the basis for subsequent post-war twin BMW engines like the R51/3, R67 and R68.
The third side-car wheel was influenced with an axle linked to the trunk wheel of the motorcycle. These were fixed with a locking differential and selectable highway and off-road gear ratios by which all and reverse gears performed. 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 rival the Z?ndapp KS 750 were both extensively used 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 after standardization of parts for both machines, with a view of eventually making 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. They also arranged that the production of the R75 would stop once production reached 20,200 units, and after that point BMW and Z?ndapp would only produce the Z?ndapp-BMW machine, processing 20,000 every year.
Since the focus on of 20,200 BMW R75's had not been reached, it continued to be in production until the Eisenach stock was so badly ruined by Allied bombing that production ceased in 1944. A further 98 models were built by the Soviets in 1946 as reparations.
