Built around Kymco's scooter motorcycle platform, the 2012 Kymco Sento 50 features a 49.5 cc (3 cu in) air-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 4 HP (2.9 kW) at 8,000 rpm, transferring power to the rear wheel through a automatic gearbox. Internal engine geometry specifies a bore and stroke of 39.0 x 41.1 mm (1.5 x 1.6 inches).
On the scales, the Sento 50 measures 89 kg (196 lbs) dry. Rider ergonomics and chassis geometry center around a 1,375 mm (54.1 in) wheelbase engineered for quick, flickable steering geometry. The 5-liter (1.3 US gal) fuel tank paired with a rated consumption of 2.7 L/100 km provides an estimated theoretical range of roughly 185 km (115 miles) between fill-ups.
