Due to the restrictions of the 1919 Treaty of Versailles, the German army could not develop many means of reconnaissance or communication, and for this reason, among other things, in the 1920s they focused on developing heavy motorcycles with good or very good on- and off-road performance. After the Nazis came to power in 1933, the process did not stop, but rather accelerated. It led to the appearance in the 1930s and during World War II of such successful designs as the BMW R-12, the BMW R75 or the Zündapp KS 750. It is worth adding that motorcycles in the German army very often had a sidecar designed for a soldier with a machine gun. Motorcycles in the German army proved themselves particularly well in the initial period of World War II, especially during the battles in Poland (1939), France (1940), and also in North Africa (1941-1943). They were used mainly for reconnaissance operations, sometimes behind enemy lines, and for communications tasks.
