Engineered by Keeway for the scooter motorcycle segment, the 2009 Keeway Matrix 150 relies on a 150.1 cc (9.2 cu in) single cylinder, two-stroke powerplant. In factory specification, peak output is rated at 9.8 HP (7.1 kW) at 7,500 rpm while maximum torque reaches 10 Nm (7.4 lb-ft) at 6,000 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 65.3 HP per liter and a 1,500 rpm working window between peak torque (6,000 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 Matrix 150 measures 102 kg (225 lbs) dry, translating to a power-to-weight ratio of 0.1 HP/kg (10.41 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,270 mm (50 in) wheelbase engineered for quick, flickable steering geometry. The 6-liter (1.6 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 88 km/h (55 mph).
