At the heart of the 2019 Honda SH125i scooter motorcycle, Honda features a 124.9 cc (7.6 cu in) liquid-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 12 HP (8.8 kW) at 8,500 rpm while maximum torque reaches 11.5 Nm (8.5 lb-ft) at 7,000 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 96.1 HP per liter and a 1,500 rpm working window between peak torque (7,000 rpm) and peak power (8,500 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 136.9 kg (302 lbs) wet (curb), translating to a power-to-weight ratio of 0.09 HP/kg (11.41 kg per horsepower). Rider ergonomics and chassis geometry center around a 799 mm (31.5 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,340 mm (52.8 in) wheelbase engineered for quick, flickable steering geometry. The 7.5-liter (2 US gal) fuel tank paired with a rated consumption of 1.76 L/100 km provides an estimated theoretical range of roughly 426 km (265 miles) between fill-ups.
