The BMW R75 is a global Conflict II-era motorcycle and sidecar blend produced by the German company BMW.
Inside the 1930s BMW were creating a amount of popular and highly effective motorcycles. In 1938 development of the R75 started in reaction to a need from the German Military.
Preproduction models of the R75 were run with a 750 cc area valve engine, that was based on the R71 engine unit. However it was quickly found essential to design an all-new OHV 750 cc engine unit for the R75 device. This OHV engine motor later became the foundation for subsequent post-war twin BMW engines like the R51/3, R67 and R68.
The 3rd side-car wheel was influenced with an axle linked to the rear wheel of the motorcycle. They were installed with a locking differential and selectable road and off-road products ratios through which all and reverse gears worked. This made the R75 highly manoeuvrable and with the capacity of negotiating most floors. 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 greatly utilized by the Wehrmacht in Russia and North Africa, though over time 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 Army, agreed upon standardization of parts for both machines, with a view of eventually making a Z?ndapp-BMW hybrid (selected the BW 43), when a BMW 286/1 side-car would be grafted onto a Z?ndapp KS 750 motorcycle. They also arranged that the produce 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 each year.
Since the target of 20,200 BMW R75's was not reached, it remained in production until the Eisenach stock was so badly damaged by Allied bombing that production ceased in 1944. A further 98 models were put together by the Soviets in 1946 as reparations.
