Technical Overview
2009 Skyteam ST250 SM Technical Analysis & Specification Breakdown
Engineered by Skyteam for the enduro - offroad motorcycle segment, the 2009 Skyteam ST250 SM utilizes a 223 cc (13.6 cu in) air-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 12 HP (8.8 kW), transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 53.8 HP per liter, the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the ST250 SM measures 123 kg (271 lbs) dry, translating to a power-to-weight ratio of 0.1 HP/kg (10.25 kg per horsepower). Rider ergonomics and chassis geometry center around a 910 mm (35.8 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control. The 10-liter (2.6 US gal) fuel tank paired with a rated consumption of 2.9 L/100 km provides an estimated theoretical range of roughly 345 km (214 miles) between fill-ups, while factory top speed is listed at 106 km/h (66 mph).
