Built around Sachs's scooter motorcycle platform, the 2008 Sachs SpeedJet 50 relies on a 49.7 cc (3 cu in) single cylinder, two-stroke powerplant. In factory specification, peak output is rated at 2.8 HP (2.1 kW) at 8,000 rpm, transferring power to the rear wheel through a automatic gearbox and shaft drive (cardan) final drive.
On the scales, the SpeedJet 50 measures 87 kg (192 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 1,290 mm (50.8 in) wheelbase engineered for quick, flickable steering geometry. The 4.7-liter (1.2 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 45 km/h (28 mph).
