BMW R 75, 750 cc (1943).
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.
This made the R75 highly manoeuvrable and capable of negotiating most surfaces. A few other motorcycle manufactures, like FN and Norton, offered optional drive to sidecars.
