Overview

Introducing the 1939 DKW SB 500A—a true gem from the golden age of motorcycling that perfectly encapsulates the spirit of the pre-war era. DKW, a pioneering German manufacturer, carved a niche in the allround motorcycle market with this versatile model, appealing to riders who sought both utility and enjoyment. The SB 500A was designed to meet the demands of everyday commuting while still providing the thrill of the open road, making it an ideal choice for both novice and experienced motorcyclists alike. At the heart of the DKW SB 500A lies a robust 494cc twin-cylinder, two-stroke engine, which delivers a delightful blend of performance and character. With its liquid cooling system and Bing carburettor, this motorcycle is not only a pleasure to ride but also surprisingly efficient for its time. Riders will appreciate the smooth power delivery that this engine provides, allowing for confident acceleration and a responsive riding experience. The foot-operated clutch and chain final drive contribute to a seamless transmission of power, ensuring that every twist of the throttle translates into exhilarating forward motion. The DKW SB 500A is equipped with features that showcase the innovative spirit of its era. The front and rear drum brakes, while simple in design, deliver reliable stopping power, ensuring that riders can navigate through various terrains with confidence. The girder fork coil spring front suspension offers excellent stability, while the rigid rear suspension provides a direct connection to the road, enhancing the overall riding experience. Adding to the convenience is the electric starter, a feature that was quite advanced for its time, making it easier for riders to get on the road without the hassle of kick-starting. ###
