2008 Keeway Speed 150 Technical Analysis & Specification Breakdown

Engineered by Keeway for the allround motorcycle segment, the 2008 Keeway Speed 150 features a 149 cc (9.1 cu in) air-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 12.7 HP (9.3 kW) at 8,500 rpm while maximum torque reaches 12 Nm (8.9 lb-ft) at 6,500 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 85.2 HP per liter and a 2,000 rpm working window between peak torque (6,500 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 150 measures 120 kg (265 lbs) dry, translating to a power-to-weight ratio of 0.11 HP/kg (9.45 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,300 mm (51.2 in) wheelbase engineered for quick, flickable steering geometry. The 11-liter (2.9 US gal) fuel tank paired with a rated consumption of 2.5 L/100 km provides an estimated theoretical range of roughly 440 km (273 miles) between fill-ups, while factory top speed is listed at 101 km/h (63 mph).
