DKW was founded in Zschopau in 1919 by Danish engineer Jorgen Rasmussen and built its first motorcycle power unit, a single-cylinder, clip-on engine for bicycle attachment, in 1921.

Designed by Hugo Ruppe, this 122cc motor was a two-stroke, and DKW would remain faithful to this engine type from then on, becoming world leaders in two-stroke design in the 1930s thanks to the prescient adoption of the Schnuerle loop-scavenge system.
The latter used flat-topped pistons rather than the then-conventional deflector-crown type, relying on carefully angled transfer ports to direct the incoming charge around the cylinder. DKW was Continental Europe’s largest motorcycle maker at this time, manufacturing a huge and diverse range of road bikes during the 1930s.
