The BMW R4 series was provided to the rebuilding Nazi German Army of World War 2 (1939-1945) as early as 1932. The motorcycles used in the war mainly fulfilled the dispatch role and various accessories could be added to further increase the tactical value of such machines. Many Wehrmacht solders trained on R4 models prior to the war and the type became an instant classic. Based on the original civilian market design, the R4 differed in incorporating a skid plate and different brackets for its saddlebags. The skid pans protected the small engine.

In practice, as well liked as the series was, it suffered from being underpowered but were nonetheless considered reliable machines - retaining nearly all qualities of their civilian counterparts.

The R4 series was succeeded by the BMW R12 of 1935 which was offered with sidecar and produced in large quantities with a more powerful engine.
