Positioned in Keeway's naked motorcycle lineup, the 2012 Keeway Speed 125 relies on a 124 cc (7.6 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 10.7 HP (7.8 kW) at 8,500 rpm while maximum torque reaches 9.9 Nm (7.3 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 86.3 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 Speed 125 measures 128 kg (282 lbs) dry, translating to a power-to-weight ratio of 0.08 HP/kg (11.96 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,320 mm (52 in) wheelbase engineered for quick, flickable steering geometry. The 15-liter (4 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 95 km/h (59 mph).
