The BMW R75 is a World Conflict II-era motorcycle and sidecar mixture made by the German company BMW.
Inside the 1930s BMW were creating a range of popular and highly effective motorcycles. In 1938 development of the R75 were only available in respond to a submission from the German Army.
Preproduction types of the R75 were run with a 750 cc part valve engine, which was predicated on the R71 engine. However it was quickly found necessary to design an all-new OHV 750 cc engine for the R75 device. This OHV engine motor later proved to be 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 equipped with a locking differential and selectable road and off-road equipment ratios by which all and reverse gears proved helpful. This made the R75 highly manoeuvrable and capable of negotiating most floors. Additional motorcycle manufactures, like FN and Norton, provided an optional drive to sidecars.
The BMW R75 and its competitor the Z?ndapp KS 750 were both generally employed by the Wehrmacht in Russia and North Africa, though after a period 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 Military, agreed upon standardization of parts for both machines, with a view of eventually making a Z?ndapp-BMW hybrid (specified the BW 43), in which a BMW 286/1 side-car would be grafted onto a Z?ndapp KS 750 motorcycle. In addition they arranged that the make of the R75 would cease once production reached 20,200 models, and after that point BMW and Z?ndapp would only produce the Z?ndapp-BMW machine, manufacturing 20,000 every year.
Since the focus on of 20,200 BMW R75's was not reached, it remained in production before Eisenach stock was so badly harmed by Allied bombing that development ceased in 1944. A further 98 units were built by the Soviets in 1946 as reparations.
