Built around DKW's sport motorcycle platform, the 1969 DKW RT 159 utilizes a 49.6 cc (3 cu in) air-cooled single cylinder, two-stroke layout. In factory specification, peak output is rated at 5.3 HP (3.9 kW) at 7,000 rpm, transferring power to the rear wheel through chain final drive. Internal engine geometry specifies a bore and stroke of 38.0 x 44.0 mm (1.5 x 1.7 inches).
On the scales, the RT 159 measures 85 kg (187 lbs) dry, translating to a power-to-weight ratio of 0.06 HP/kg (16.04 kg per horsepower). Rider ergonomics and chassis geometry center around a 760 mm (29.9 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops. The 13-liter (3.4 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 80 km/h (50 mph).
