Positioned in Honda's scooter motorcycle lineup, the 2022 Honda RS125 relies on a 125 cc (7.6 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 9.6 HP (7 kW) at 7,500 rpm while maximum torque reaches 9.6 Nm (7 lb-ft) at 6,500 rpm, transferring power to the rear wheel through a 4-speed gearbox and belt final drive. With a specific output of 76.8 HP per liter and a 1,000 rpm working window between peak torque (6,500 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 RS125 measures 104 kg (229 lbs) dry, translating to a power-to-weight ratio of 0.09 HP/kg (10.83 kg per horsepower). Rider ergonomics and chassis geometry center around a 767 mm (30.2 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,228 mm (48.3 in) wheelbase engineered for quick, flickable steering geometry. The 3.9-liter (1 US gal) fuel tank supports practical everyday commuting and weekend road stints.
