Positioned in Skyteam's allround motorcycle lineup, the 2014 Skyteam ST125 Bubbly features a 123 cc (7.5 cu in) air-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 8.5 HP (6.2 kW) at 5,500 rpm while maximum torque reaches 8.8 Nm (6.5 lb-ft) at 5,500 rpm, transferring power to the rear wheel through a 4-speed gearbox and chain final drive. With a specific output of 69.1 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 Bubbly measures 80 kg (176 lbs) dry, translating to a power-to-weight ratio of 0.11 HP/kg (9.41 kg per horsepower). Rider ergonomics and chassis geometry center around a 770 mm (30.3 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,090 mm (42.9 in) wheelbase engineered for quick, flickable steering geometry. The 6.2-liter (1.6 US gal) fuel tank supports practical everyday commuting and weekend road stints.
