Built around Keeway's scooter motorcycle platform, the 2008 Keeway F-Act 50 relies on a 49.3 cc (3 cu in) 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). Internal engine geometry specifies a bore and stroke of 40.3 x 39.0 mm (1.6 x 1.5 inches).
On the scales, the F-Act 50 measures 86 kg (190 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 4 indexed model years from 2007 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.
