Technical Overview
2024 Keeway RK 125 E Technical Analysis & Specification Breakdown
Engineered by Keeway for the sport motorcycle segment, the 2024 Keeway RK 125 E features a 124.8 cc (7.6 cu in) air-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 11 HP (8 kW) at 8,500 rpm while maximum torque reaches 9.2 Nm (6.8 lb-ft) at 7,500 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 88.1 HP per liter and a 1,000 rpm working window between peak torque (7,500 rpm) and peak power (8,500 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 RK 125 E measures 105 kg (231 lbs) dry, translating to a power-to-weight ratio of 0.1 HP/kg (9.55 kg per horsepower). Rider ergonomics and chassis geometry center around a 730 mm (28.7 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,250 mm (49.2 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, while factory top speed is listed at 90 km/h (56 mph).
