At the heart of the 2012 Sachs SpeedJet RS 50 scooter motorcycle, Sachs pairs a 49 cc (3 cu in) air-cooled single cylinder, two-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 3.1 HP (2.2 kW) at 6,000 rpm, transferring power to the rear wheel through a automatic gearbox and chain final drive.
On the scales, the SpeedJet RS 50 measures 90 kg (198 lbs) dry. Rider ergonomics and chassis geometry center around a 800 mm (31.5 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,320 mm (52 in) wheelbase engineered for quick, flickable steering geometry. The 6-liter (1.6 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 45 km/h (28 mph).
