Description

Extreme cosplay :-)
The BMW R75 is a World War II-era motorcycle and sidecar combination produced by the German company BMW. Development of the R75 started in 1938, in response to a request from the German Army. 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 twin BMW engines like the R51/3, R67 and R68. The third side-car wheel was driven with an axle connected to the rear wheel of the motorcycle. These were fitted with a locking differential and selectable road and off-road gear ratios through which all four and reverse gears worked. This made the R75 highly maneuverable and capable of negotiating most surfaces.  
The success and reliability of the shaft-driven R75 during the war led to the US Army requesting that Harley-Davidson produce a similar shaft-driven cycle for American troops. This led to Harley producing their first ever shaft-driven model, the Harley-Davidson XA, which was a near duplicate of the R75 Source: Wikipedia (I got lazy!)

Excellent shot, the Germans were very big on their military motorcycles.  That MG42 makes that rig a nasty customer until something hits it.
