Positioned in Keeway's scooter motorcycle lineup, the 2009 Keeway F-Act 125 utilizes a 124.6 cc (7.6 cu in) air-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 8.6 HP (6.3 kW) at 7,500 rpm while maximum torque reaches 8.3 Nm (6.1 lb-ft) at 6,500 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 69 HP per liter and a 1,000 rpm working window between peak torque (6,500 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 F-Act 125 measures 102 kg (225 lbs) dry, translating to a power-to-weight ratio of 0.08 HP/kg (11.86 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,283 mm (50.5 in) wheelbase engineered for quick, flickable steering geometry. The 5-liter (1.3 US gal) fuel tank paired with a rated consumption of 2.8 L/100 km provides an estimated theoretical range of roughly 179 km (111 miles) between fill-ups, while factory top speed is listed at 86 km/h (53 mph).
