After the Second World War, the successful supercharged machines of the pre-war era are only allowed to participate in national races, and supercharged engines are no longer permitted in international competitions after 1945. Until a complete redesign, the supercharger of this victorious pre-war racing machine is simply amputated, and the motorcycle is converted to a naturally aspirated dual-carburetor variant, completely sufficient in order to win the German Championship in 1951.
