At the heart of the 2019 Honda CB125F sport motorcycle, Honda utilizes a 124.7 cc (7.6 cu in) air-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 10.5 HP (7.6 kW) at 7,750 rpm while maximum torque reaches 10.2 Nm (7.5 lb-ft) at 6,250 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 84.2 HP per liter and a 1,500 rpm working window between peak torque (6,250 rpm) and peak power (7,750 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 CB125F measures 128 kg (282 lbs) wet (curb), translating to a power-to-weight ratio of 0.08 HP/kg (12.19 kg per horsepower). Rider ergonomics and chassis geometry center around a 775 mm (30.5 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,295 mm (51 in) wheelbase engineered for quick, flickable steering geometry. The 13-liter (3.4 US gal) fuel tank paired with a rated consumption of 1.56 L/100 km provides an estimated theoretical range of roughly 833 km (518 miles) between fill-ups.
