The classic German DKW RT (Reichstyp: "National Model") 125 has the distinction of being the most copied motorcycle in the world. The power unit, a simple single-cylinder 2-stroke, was the most advanced and efficient design at the time. At the end of WWII the blueprints were made available to the Allies, and the design soon bore such familiar names as BSA Bantam, Harley-Davidson Hummer, Maserati, Soviet Moska and Yamaha YA-1.
