History
The BMW R75 along with the Zundapp KS 750 was developed in response to a request from the German Army during World War II. It was powered by a 750 cc horizontally opposed, two cylinder engine based on the R12 gasoline engine featuring overhead valves. The rear wheel featured a locking differential (with two gear ratios for road or off road) and power take off (PTO) for a driven sidecar wheel.
BMW and Zündapp upon the urging of the Wehrmacht, agreed upon standardization of parts for both machines. The standardization program meant that machines that were produced by BMW and Zündapp used almost 70% of the same components. This simplifies the supply of spare parts for these vehicles, many of which are still in the hands of historic motorcycle enthusiasts. These vehicles are desirable as collector's items because of their complex and durable technology. Many well restored examples can be found on the road today.
