1973 BMW R75/5 Motorcycle Review

The BMW R75 is a global Warfare 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 response to a request from the German Military.

Preproduction models of the R75 were driven by way of a 750 cc aspect valve engine, that was based on the R71 engine. 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 foundation for following post-war twin BMW engines like the R51/3, R67 and R68.

The third side-car wheel was motivated with an axle connected to the trunk wheel of the motorcycle. These were installed with a locking differential and selectable highway and off-road gear ratios through which all and reverse gears worked. This made the R75 highly manoeuvrable and with the capacity of negotiating most surfaces. Additional 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 extensively utilized by the Wehrmacht in Russia and North Africa, though after a period 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 after standardization of parts for both machines, with a view of eventually setting up 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. In addition they agreed that the make of the R75 would stop once production reached 20,200 systems, and after that point BMW and Z?ndapp would only produce the Z?ndapp-BMW machine, making 20,000 each year.

Since the target of 20,200 BMW R75's was not reached, it continued to be in production until the Eisenach stock was so badly harmed by Allied bombing that creation ceased in 1944. An additional 98 systems were put together by the Soviets in 1946 as reparations.
