Engineered by Skyteam for the custom - cruiser motorcycle segment, the 2009 Skyteam ST125-11 pairs a 124 cc (7.6 cu in) air-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 6.7 HP (4.9 kW) at 5,500 rpm while maximum torque reaches 7.3 Nm (5.4 lb-ft) at 6,500 rpm, transferring power to the rear wheel through a 4-speed gearbox and chain final drive. With a specific output of 54 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 ST125-11 measures 88 kg (194 lbs) dry, translating to a power-to-weight ratio of 0.08 HP/kg (13.13 kg per horsepower). Rider ergonomics and chassis geometry center around a 760 mm (29.9 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,200 mm (47.2 in) wheelbase engineered for quick, flickable steering geometry. The 4.5-liter (1.2 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 82 km/h (51 mph).
