Built around Keeway's scooter motorcycle platform, the 2007 Keeway Matrix 50 relies on a 49.3 cc (3 cu in) air-cooled single cylinder, two-stroke powerplant. In factory specification, peak output is rated at 3.4 HP (2.5 kW) at 7,000 rpm while maximum torque reaches 3.9 Nm (2.9 lb-ft) at 7,000 rpm, transferring power to the rear wheel through a automatic gearbox. Internal engine geometry specifies a bore and stroke of 40.0 x 39.2 mm (1.6 x 1.5 inches) with a 6.9:1 compression ratio.
On the scales, the Matrix 50 measures 93 kg (205 lbs) dry. Rider ergonomics and chassis geometry center around a 1,270 mm (50 in) wheelbase engineered for quick, flickable steering geometry. The 4.8-liter (1.3 US gal) fuel tank paired with a rated consumption of 2 L/100 km provides an estimated theoretical range of roughly 240 km (149 miles) between fill-ups, while factory top speed is listed at 45 km/h (28 mph).
Within MotoLibrary's Keeway archive, this model family spans 5 indexed model years from 2006 to 2010, allowing buyers to track year-over-year changes in emissions tuning, weight and equipment.

Use this page to compare this motorcycle by its real specifications, not only by model name. Focus on the details that affect fit, comfort, handling, range and ownership.
Power
Compare engine output with similar motorcycles if acceleration, highway use or two-up riding matters.
Torque
Torque is useful for judging real-world pull, especially for touring, commuting and loaded riding.
Weight
Compare weight carefully because it affects low-speed handling, parking and confidence.
Fuel Capacity
Fuel capacity helps estimate touring range and how often you may need to stop.
Brakes
Brake setup is worth comparing if you ride in traffic, mountains or with a passenger.
Transmission
Transmission and final drive affect maintenance, smoothness and everyday usability.
