Engineered by Honda for the scooter motorcycle segment, the 2010 Honda SH125i features a 125 cc (7.6 cu in) liquid-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 13 HP (9.5 kW) at 9,000 rpm while maximum torque reaches 11.5 Nm (8.5 lb-ft) at 7,000 rpm, transferring power to the rear wheel through belt final drive. With a specific output of 104 HP per liter and a 2,000 rpm working window between peak torque (7,000 rpm) and peak power (9,000 rpm), the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.
On the scales, the SH125i measures 120 kg (265 lbs) dry, translating to a power-to-weight ratio of 0.11 HP/kg (9.23 kg per horsepower). Rider ergonomics and chassis geometry center around a 790 mm (31.1 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,335 mm (52.6 in) wheelbase engineered for quick, flickable steering geometry. The 7.5-liter (2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
