Engineered by Honda for the scooter motorcycle segment, the 2012 Honda SH300i utilizes a 279.1 cc (17 cu in) liquid-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 26.8 HP (19.6 kW) at 8,250 rpm while maximum torque reaches 26 Nm (19.2 lb-ft) at 6,000 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 96 HP per liter and a 2,250 rpm working window between peak torque (6,000 rpm) and peak power (8,250 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 SH300i measures 161.8 kg (357 lbs) dry, translating to a power-to-weight ratio of 0.17 HP/kg (6.04 kg per horsepower). Rider ergonomics and chassis geometry center around a 785 mm (30.9 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,420 mm (55.9 in) wheelbase engineered for balanced agility and highway composure. The 9-liter (2.4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
