Engineered by Keeway for the naked motorcycle segment, the 2012 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 10.6 HP (7.7 kW) at 8,250 rpm while maximum torque reaches 10.4 Nm (7.7 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 71.1 HP per liter and a 1,750 rpm working window between peak torque (6,500 rpm) and peak power (8,250 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 142 kg (313 lbs) wet (curb), translating to a power-to-weight ratio of 0.07 HP/kg (13.4 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 100 km/h (62 mph).
