Engineered by Honda for the scooter motorcycle segment, the 2007 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 11.7 Nm (8.6 lb-ft) at 8,500 rpm, transferring power to the rear wheel through a 4-speed gearbox and belt final drive. With a specific output of 108 HP per liter and a 500 rpm working window between peak torque (8,500 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 139.9 kg (308 lbs) dry, translating to a power-to-weight ratio of 0.1 HP/kg (10.36 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 1,490 mm (58.7 in) wheelbase engineered for balanced agility and highway composure. The 9.4-liter (2.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
