The BMW R75 is a World Warfare II-era motorcycle and sidecar combo made by the German company BMW.
Inside the 1930s BMW were creating a number of popular and highly effective motorcycles. In 1938 development of the R75 were only available in reaction to a get from the German Military.
Preproduction types of the R75 were powered by way of a 750 cc area valve engine, which was based on the R71 engine. Nonetheless it was quickly found necessary to design an all-new OHV 750 cc engine unit for the R75 unit. 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 motivated with an axle linked to the rear wheel of the motorcycle. These were fitted with a locking differential and selectable highway and off-road items ratios by which all four and change gears proved helpful. This made the R75 highly manoeuvrable and capable of negotiating most areas. 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 broadly used 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 Military, agreed upon standardization of parts for both machines, with a view of eventually developing a Z?ndapp-BMW hybrid (chosen the BW 43), in which a BMW 286/1 side-car would be grafted onto a Z?ndapp KS 750 motorcycle. In addition they decided that the production of the R75 would stop once production reached 20,200 systems, and from then on point BMW and Z?ndapp would only produce the Z?ndapp-BMW machine, manufacturing 20,000 each year.
Since the concentrate on of 20,200 BMW R75's had not been reached, it remained in production before Eisenach manufacturing plant was so badly harmed by Allied bombing that production ceased in 1944. An additional 98 items were assembled by the Soviets in 1946 as reparations.
