Technical Overview
2023 Honda Supra GTR150 Technical Analysis & Specification Breakdown
Engineered by Honda for the scooter motorcycle segment, the 2023 Honda Supra GTR150 pairs a 150 cc (9.2 cu in) liquid-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 15.4 HP (11.3 kW) at 9,000 rpm while maximum torque reaches 13.6 Nm (10 lb-ft) at 6,700 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 102.7 HP per liter and a 2,300 rpm working window between peak torque (6,700 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 Supra GTR150 measures 121 kg (267 lbs) wet (curb), translating to a power-to-weight ratio of 0.13 HP/kg (7.86 kg per horsepower). Rider ergonomics and chassis geometry center around a 786 mm (30.9 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,276 mm (50.2 in) wheelbase engineered for quick, flickable steering geometry. The 4.5-liter (1.2 US gal) fuel tank paired with a rated consumption of 1.5 L/100 km provides an estimated theoretical range of roughly 300 km (186 miles) between fill-ups.
