2006 Keeway Speed 125 Technical Analysis & Specification Breakdown

At the heart of the 2006 Keeway Speed 125 sport motorcycle, Keeway utilizes a 124.6 cc (7.6 cu in) air-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 7 HP (5.1 kW) at 7,500 rpm while maximum torque reaches 7.4 Nm (5.5 lb-ft) at 4,750 rpm, transferring power to the rear wheel through chain final drive. With a specific output of 56.2 HP per liter and a 2,750 rpm working window between peak torque (4,750 rpm) and peak power (7,500 rpm), the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.

On the scales, the Speed 125 measures 105 kg (231 lbs) dry, translating to a power-to-weight ratio of 0.07 HP/kg (15 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,270 mm (50 in) wheelbase engineered for quick, flickable steering geometry. The 5.2-liter (1.4 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 86 km/h (53 mph).
