Built around DKW's allround motorcycle platform, the 1934 DKW SB 500A features a 494 cc (30.1 cu in) twin, two-stroke configuration. Internal engine geometry specifies a bore and stroke of 68.0 x 68.0 mm (2.7 x 2.7 inches) with a 5.7:1 compression ratio.
On the scales, the SB 500A measures 235 kg (518 lbs) dry. Rider ergonomics and chassis geometry center around a 675 mm (26.6 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,385 mm (54.5 in) wheelbase engineered for quick, flickable steering geometry. 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).
