Engineered by Keeway for the scooter motorcycle segment, the 2015 Keeway CS 125 features a 124.8 cc (7.6 cu in) air-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 8.7 HP (6.4 kW) at 7,000 rpm while maximum torque reaches 9.5 Nm (7 lb-ft) at 6,500 rpm, transferring power to the rear wheel through a 4-speed gearbox and chain final drive. With a specific output of 69.7 HP per liter and a 500 rpm working window between peak torque (6,500 rpm) and peak power (7,000 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 CS 125 measures 98 kg (216 lbs) dry, translating to a power-to-weight ratio of 0.09 HP/kg (11.26 kg per horsepower). Rider ergonomics and chassis geometry center around a 770 mm (30.3 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,225 mm (48.2 in) wheelbase engineered for quick, flickable steering geometry. The 7-liter (1.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
