Positioned in Honda's scooter motorcycle lineup, the 2011 Honda PS125i utilizes a 125 cc (7.6 cu in) liquid-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 13.5 HP (9.9 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 108 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 PS125i measures 135 kg (298 lbs) dry, translating to a power-to-weight ratio of 0.1 HP/kg (10 kg per horsepower). Rider ergonomics and chassis geometry center around a 800 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 8-liter (2.1 US gal) fuel tank supports practical everyday commuting and weekend road stints.
