2018 Honda SH300i Technical Analysis & Specification Breakdown

Engineered by Honda for the scooter motorcycle segment, the 2018 Honda SH300i pairs a 279.1 cc (17 cu in) liquid-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 24.8 HP (18.1 kW) at 7,500 rpm while maximum torque reaches 25.5 Nm (18.8 lb-ft) at 5,000 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 88.9 HP per liter and a 2,500 rpm working window between peak torque (5,000 rpm) and peak power (7,500 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.

On the scales, the SH300i measures 169 kg (373 lbs) wet (curb), translating to a power-to-weight ratio of 0.15 HP/kg (6.81 kg per horsepower). Rider ergonomics and chassis geometry center around a 805 mm (31.7 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,438 mm (56.6 in) wheelbase engineered for balanced agility and highway composure. The 9-liter (2.4 US gal) fuel tank paired with a rated consumption of 2.5 L/100 km provides an estimated theoretical range of roughly 360 km (224 miles) between fill-ups, while factory top speed is listed at 128 km/h (80 mph).
