At the heart of the 2010 Yiben YB50QT-3 scooter motorcycle, Yiben relies on a 49.5 cc (3 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 3.8 HP (2.7 kW) at 8,000 rpm while maximum torque reaches 3.4 Nm (2.5 lb-ft) at 6,500 rpm, transferring power to the rear wheel through shaft drive (cardan) final drive.
On the scales, the YB50QT-3 measures 90 kg (198 lbs) dry. Rider ergonomics and chassis geometry center around a 1,190 mm (46.9 in) wheelbase engineered for quick, flickable steering geometry. The 5-liter (1.3 US gal) fuel tank paired with a rated consumption of 2.1 L/100 km provides an estimated theoretical range of roughly 238 km (148 miles) between fill-ups, while factory top speed is listed at 60 km/h (37 mph).
