The BMW R75 is a global Conflict II-era motorcycle and sidecar mixture made by the German company BMW.
Inside the 1930s BMW were producing a quantity of popular and impressive motorcycles. In 1938 development of the R75 were only available in reaction to a submission from the German Military.
Preproduction models of the R75 were powered with a 750 cc area valve engine, which was predicated on the R71 engine motor. Nonetheless it was quickly found essential to design an all-new OHV 750 cc engine unit for the R75 unit. This OHV engine later proved to be the basis for succeeding post-war twin BMW engines like the R51/3, R67 and R68.
The third side-car wheel was motivated with an axle connected to the trunk wheel of the motorcycle. These were built in with a locking differential and selectable highway and off-road gear ratios through which all four and change gears did the trick. This made the R75 highly manoeuvrable and capable 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 extensively used by the Wehrmacht in Russia and North Africa, though over time 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 Army, agreed upon standardization of parts for both machines, with a view of eventually setting up a Z?ndapp-BMW hybrid (selected the BW 43), in which a BMW 286/1 side-car would be grafted onto a Z?ndapp KS 750 motorcycle. They also decided that the produce of the R75 would stop once production come to 20,200 products, 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 remained in production until the Eisenach manufacturing plant was so badly broken by Allied bombing that development ceased in 1944. An additional 98 units were assembled by the Soviets in 1946 as reparations.
