During [[World War II]], the BMW motorcycle copies of the [[Zündapp]] KS750 performed exceptionally well in the harsh environment of the North African deserts. At the beginning of the war, the German army needed as many vehicles as it could get of all types. Although motorcycles of every style performed acceptably well in Europe, in the desert the protruding cylinders of the [[flat-twin]] engine and shaft drive performed better than vertical and V-twin engines, which overheated in the hot air, and chain-drives, which were damaged by desert sand.

Also during World War II, the U.S. Army asked Harley-Davidson, [[Indian 841|Indian]], [[Delco Electronics|Delco]], and [[Crossley]]{{Fact|date=April 2007}} to produce a motorcycle similar to the [[Flathead engine|side-valve]] BMW R71. Harley copied the BMW engine and transmission — simply converting metric measurements to inches — and produced the shaft-drive 750&nbsp;cc 1942 [[Harley-Davidson XA]].<ref>[http://www.motorcyclemuseum.org/classics/bike.asp?id=71 Harley XA], The Motorcycle Museum</ref>

The R-series and K-series use the Telelever and the Duolever front suspensions.
