Perhaps the most famous of the 600cc class bikes deployed by the German military in WWII, the KS600 was built around a 28hp horizontally opposed engine with shaft drive. With a sidecar attached, it could reach up to 96km/h and thanks to its 15-liter fuel tank had a range of 300km. Production began in 1938, and it was used in dispatch and reconnaissance roles from the early stages of WWII; although production ceased in 1941, the remaining KS600s stayed in service until the second half of the conflict.
