Zündapp KS 600 German Motorcycle

The Zündapp KS600, first released in 1938, had a 28 hp (21 kW) horizontally opposed twin cylinder motor with overhead valves displacing 597 cc (36.4 cu in). The KS600 was often coupled with a Steib sidecar, the BW38 (Beiwagen 1938). The BW38, fitted with the B1 (Boot no. 1) sidecar body was produced between 1938 and 1941 and supplied exclusively to the Wehrmacht. While the KS600 was discontinued and eventually replaced by the purpose-built KS750, its motor was to be the only remnant to live beyond the destruction of war. When Zündapp returned to motorcycle production in the late 1940s, it chose to reuse the KS600's motor to power the KS601 with few modifications.
