Technical Overview
2009 Skyteam ST125 SM Technical Analysis & Specification Breakdown
At the heart of the 2009 Skyteam ST125 SM super motard motorcycle, Skyteam relies on a 124 cc (7.6 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 10.7 HP (7.8 kW), transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 86.3 HP per liter, the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the ST125 SM measures 123 kg (271 lbs) dry, translating to a power-to-weight ratio of 0.09 HP/kg (11.5 kg per horsepower). Rider ergonomics and chassis geometry center around a 890 mm (35 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,460 mm (57.5 in) wheelbase engineered for balanced agility and highway composure. The 10-liter (2.6 US gal) fuel tank supports practical everyday commuting and weekend road stints.
