Built around DKW's allround motorcycle platform, the 1936 DKW SB 500 relies on a 493.9 cc (30.1 cu in) air-cooled twin, two-stroke powerplant. In factory specification, peak output is rated at 15 HP (10.9 kW) at 4,000 rpm, transferring power to the rear wheel through chain final drive. With a specific output of 30.4 HP per liter, the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the SB 500 measures 165 kg (364 lbs) dry, translating to a power-to-weight ratio of 0.09 HP/kg (11 kg per horsepower). The 13-liter (3.4 US gal) fuel tank paired with a rated consumption of 3.5 L/100 km provides an estimated theoretical range of roughly 371 km (231 miles) between fill-ups, while factory top speed is listed at 115 km/h (71 mph).
