Positioned in Honda's scooter motorcycle lineup, the 2015 Honda RS 125 relies on a 124.8 cc (7.6 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 9.4 HP (6.9 kW) at 7,500 rpm while maximum torque reaches 10.4 Nm (7.7 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 75.3 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 RS 125 measures 96.3 kg (212 lbs) dry, translating to a power-to-weight ratio of 0.1 HP/kg (10.24 kg per horsepower). Rider ergonomics and chassis geometry center around a 776 mm (30.6 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,237 mm (48.7 in) wheelbase engineered for quick, flickable steering geometry. The 3.8-liter (1 US gal) fuel tank supports practical everyday commuting and weekend road stints.
