The BMW R75 is a World War II-era motorcycle and sidecar combination produced by the German company BMW. The BMW R75 stands out by its integral two-wheel drive design, with drive shafts to both its rear wheel and the third side-car wheel, from a locking differential, as well as a transfer case offering both road and off-road gear ratios, through which all forward and reverse gears worked.

The R75 represented the spearhead of the super-heavy combinations at BMW. The construction was intended exclusively for hard wartime use. Accordingly, the machines were considered very robust and almost indestructible.
This piece of war history was produced on June 15, 1943 and delivered to the Army Stuff Office in Chemnitz, Germany, on the same day. The crankshaft was completely overhauled last year. Nothing stands in the way of a longer trip. The R75 is ready to drive.

Preproduction models of the R75 were powered by a 750 cc side valve engine, which was based on the R71 engine. However it was quickly found necessary to design an all-new OHV 750 cc engine for the R75 unit. This OHV engine later proved to be the basis for subsequent post-war BMW flat-twin engined motorcycles like the R51/3, R67 and R68.
