At the heart of the 2007 Jinlun JL QT-50-4 scooter motorcycle, Jinlun features a 49.5 cc (3 cu in) air-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 2.3 HP (1.7 kW) at 7,500 rpm while maximum torque reaches 3 Nm (2.2 lb-ft) at 6,000 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. Internal engine geometry specifies a bore and stroke of 39.0 x 41.5 mm (1.5 x 1.6 inches) with a 10.5:1 compression ratio.
On the scales, the JL QT-50-4 measures 85 kg (187 lbs) dry. Rider ergonomics and chassis geometry center around a 1,280 mm (50.4 in) wheelbase engineered for quick, flickable steering geometry. The 4.5-liter (1.2 US gal) fuel tank paired with a rated consumption of 2 L/100 km provides an estimated theoretical range of roughly 225 km (140 miles) between fill-ups, while factory top speed is listed at 45 km/h (28 mph).
