The BMW R75 is a World Conflict II-era motorcycle and sidecar combination made by the German company BMW.
Inside the 1930s BMW were producing a range of popular and impressive motorcycles. In 1938 development of the R75 started in reaction to a need from the German Military.
Preproduction types of the R75 were power by a 750 cc part valve engine, that was predicated on the R71 engine unit. Nonetheless it was quickly found necessary to design an all-new OHV 750 cc engine unit for the R75 device. This OHV engine unit later proved to be the foundation for following post-war twin BMW engines like the R51/3, R67 and R68.
The third side-car wheel was powered with an axle connected to the trunk wheel of the motorcycle. They were fitted with a locking differential and selectable highway and off-road items ratios by which all and change gears functioned. This made the R75 highly manoeuvrable and with the capacity of negotiating most areas. 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 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 upon standardization of parts for both machines, with a view of eventually making a Z?ndapp-BMW hybrid (specified the BW 43), when a BMW 286/1 side-car would be grafted onto a Z?ndapp KS 750 motorcycle. In addition they arranged that the manufacture of the R75 would cease once production come to 20,200 systems, and from then on point BMW and Z?ndapp would only produce the Z?ndapp-BMW machine, developing 20,000 every 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 terribly destroyed by Allied bombing that production ceased in 1944. An additional 98 units were built by the Soviets in 1946 as reparations.
