The 1938 DKW SB 500: A Classic Allrounder

Step back in time to 1938, a pivotal year in motorcycle history, when DKW introduced the SB 500—a machine that captured the spirit of versatility and innovation. Positioned as an allround motorcycle, the SB 500 was designed to cater to a wide range of riders, from commuters to leisure enthusiasts. Its robust engineering and practical design made it a popular choice in the pre-war era, as it appealed to those seeking both functionality and flair on two wheels. With a weight of just 165 kg, this motorcycle offered a blend of agility and stability, ensuring riders could confidently navigate diverse terrain.

At the heart of the SB 500 lies a 493.90 ccm twin-cylinder, two-stroke engine, which delivers a respectable 15 horsepower at 4,000 RPM. This powerplant, with its air-cooled design and a compression ratio of 5.7:1, provides a thrilling ride, allowing the motorcycle to reach a top speed of 115 km/h (71.5 mph). Riders will appreciate the smoothness of the Amal carburetor that efficiently delivers fuel to the engine, making for a responsive throttle that enhances the overall riding experience. The power-to-weight ratio of 0.0909 HP/kg ensures that the SB 500 feels lively and engaging, whether zipping through city streets or cruising along country roads.

The DKW SB 500 is not just about performance; it embodies the technology of its time with features that enhance both safety and comfort. The motorcycle is equipped with drum brakes—expanding brakes both front and rear—that provide reliable stopping power, a critical feature for riders of all skill levels. The rigid rear suspension offers a straightforward design that contributes to the motorcycle's durability, ensuring that it stands the test of time. The 13-litre fuel capacity allows for extended rides without frequent stops, making it an ideal companion for day-long adventures.
