Positioned in Keeway's naked motorcycle lineup, the 2022 Keeway RKF 125 pairs a 125 cc (7.6 cu in) liquid-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 12.6 HP (9.2 kW) at 9,500 rpm while maximum torque reaches 10 Nm (7.4 lb-ft) at 8,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 100.8 HP per liter and a 1,000 rpm working window between peak torque (8,500 rpm) and peak power (9,500 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 RKF 125 measures 147 kg (324 lbs) dry, translating to a power-to-weight ratio of 0.09 HP/kg (11.67 kg per horsepower). Rider ergonomics and chassis geometry center around a 810 mm (31.9 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,345 mm (53 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.
