The BMW R75 is a global Conflict II-era motorcycle and sidecar combination produced by the German company BMW.
Within the 1930s BMW were creating a quantity of popular and highly effective motorcycles. In 1938 development of the R75 were only available in reaction to a request from the German Army.
Preproduction types of the R75 were powered by way of a 750 cc aspect valve engine, that was based on the R71 engine motor. Nonetheless it was quickly found necessary to design an all-new OHV 750 cc engine motor for the R75 product. This OHV engine unit later became the basis for following post-war twin BMW engines like the R51/3, R67 and R68.
The 3rd side-car wheel was motivated with an axle linked to the rear wheel of the motorcycle. They were fixed with a locking differential and selectable highway and off-road products ratios by which all and change gears worked well. This made the R75 highly manoeuvrable and capable of negotiating most surfaces. 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 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 creating 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. They also decided that the manufacture of the R75 would cease once production come to 20,200 models, 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 remained in production before Eisenach factory was so badly damaged by Allied bombing that production ceased in 1944. A further 98 products were assembled by the Soviets in 1946 as reparations.
