The BMW R75 is a World Warfare II-era motorcycle and sidecar combo produced by the German company BMW.
Inside the 1930s BMW were creating a variety of popular and impressive motorcycles. In 1938 development of the R75 started in reaction to a need from the German Army.
Preproduction models of the R75 were power by a 750 cc aspect valve engine, that was based on the R71 engine unit. However it was quickly found necessary to design an all-new OHV 750 cc engine motor for the R75 unit. This OHV engine motor later became the foundation for succeeding post-war twin BMW engines like the R51/3, R67 and R68.
The 3rd side-car wheel was motivated with an axle connected to the trunk wheel of the motorcycle. We were holding equipped with a locking differential and selectable highway and off-road equipment ratios by which all four and reverse gears proved helpful. This made the R75 highly manoeuvrable and with the capacity of negotiating most areas. A few other motorcycle manufactures, like FN and Norton, provided an optional drive to sidecars.
The BMW R75 and its rival 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 Military, agreed upon standardization of parts for both machines, with a view of eventually building a Z?ndapp-BMW hybrid (chosen 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 make of the R75 would stop once production reached 20,200 products, and from then on point BMW and Z?ndapp would only produce the Z?ndapp-BMW machine, manufacturing 20,000 every year.
Since the target of 20,200 BMW R75's was not reached, it remained in production before Eisenach factory was so badly harmed by Allied bombing that creation ceased in 1944. A further 98 items were constructed by the Soviets in 1946 as reparations.
