At the heart of the 2025 Honda Stunner sport motorcycle, Honda pairs a 124.7 cc (7.6 cu in) air-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 11 HP (8 kW) at 8,000 rpm while maximum torque reaches 11 Nm (8.1 lb-ft) at 6,500 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 88.2 HP per liter and a 1,500 rpm working window between peak torque (6,500 rpm) and peak power (8,000 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 Stunner measures 128 kg (282 lbs) dry, translating to a power-to-weight ratio of 0.09 HP/kg (11.64 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,271 mm (50 in) wheelbase engineered for quick, flickable steering geometry. The 10-liter (2.6 US gal) fuel tank supports practical everyday commuting and weekend road stints.
