Engineered by Sachs for the scooter motorcycle segment, the 2013 Sachs MadAss 50 features a 49.5 cc (3 cu in) air-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 2.6 HP (1.9 kW) at 6,972 rpm, transferring power to the rear wheel through a 4-speed gearbox and belt final drive. Internal engine geometry specifies a bore and stroke of 39.0 x 41.1 mm (1.5 x 1.6 inches) with a 10.0:1 compression ratio.
On the scales, the MadAss 50 measures 85 kg (187 lbs) dry. Rider ergonomics and chassis geometry center around a 835 mm (32.9 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,235 mm (48.6 in) wheelbase engineered for quick, flickable steering geometry. The 5-liter (1.3 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 45 km/h (28 mph).
