The BMW R75 is a global Conflict II-era motorcycle and sidecar combination 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 request from the German Military.
Preproduction types of the R75 were driven by way of a 750 cc aspect valve engine, which was based on the R71 engine motor. However it was quickly found necessary to design an all-new OHV 750 cc engine unit for the R75 device. This OHV engine motor later became the basis for succeeding post-war twin BMW engines like the R51/3, R67 and R68.
The third side-car wheel was powered with an axle linked to the rear wheel of the motorcycle. They were equipped with a locking differential and selectable road and off-road products ratios by which all four and change gears worked. 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 own competitor 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 (designated the BW 43), when a BMW 286/1 side-car would be grafted onto a Z?ndapp KS 750 motorcycle. They also decided that the make of the R75 would cease once production come to 20,200 products, and from then on 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 had not been reached, it remained in production until the Eisenach manufacturer was so badly broken by Allied bombing that production ceased in 1944. An additional 98 units were assembled by the Soviets in 1946 as reparations.
