These pics were taken at the Audi Museum in Munich. It’s a stunning 1939 US 250 DKW. The German company DKW where once the largest manufacturers of motorcycles in the world. By 1928 they were building some 65,000 engine units annually, and DKW engines could be found powering some 60 German marques of the interwar period. They soon joined Audi, Wanderer and Horch to form Auto Union in the 1930s, merging again in the 1950s with Victoria and Express to form Zweirad-Union, which in turn was absorbed by Sachs in 1965. DKW motorcycles usually used two-stroke engines and were technically ahead of their time (like most German motoring companies).
