Built around Sachs's scooter motorcycle platform, the 2013 Sachs SX pairs a 49 cc (3 cu in) single cylinder, two-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 3.9 HP (2.8 kW) at 6,500 rpm while maximum torque reaches 4.3 Nm (3.2 lb-ft) at 6,000 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. Internal engine geometry specifies a 6.9:1 compression ratio.
On the scales, the SX measures 108 kg (238 lbs) dry. Rider ergonomics and chassis geometry center around a 810 mm (31.9 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,285 mm (50.6 in) wheelbase engineered for quick, flickable steering geometry. The 5.8-liter (1.5 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 45 km/h (28 mph).
