At the heart of the 2009 Keeway Hacker 50 scooter motorcycle, Keeway relies on a 49.3 cc (3 cu in) air-cooled single cylinder, two-stroke powerplant. 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 Hacker 50 measures 115 kg (254 lbs) dry. Rider ergonomics and chassis geometry center around a 1,270 mm (50 in) wheelbase engineered for quick, flickable steering geometry. The 8-liter (2.1 US gal) fuel tank paired with a rated consumption of 2 L/100 km provides an estimated theoretical range of roughly 400 km (249 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 2 indexed model years from 2009 to 2010, allowing buyers to track year-over-year changes in emissions tuning, weight and equipment.
