Built around Jinlun's scooter motorcycle platform, the 2007 Jinlun JL 50QT-5 Commuter relies on a 49.5 cc (3 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 3.1 HP (2.2 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. 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 50QT-5 Commuter measures 75 kg (165 lbs) dry. Rider ergonomics and chassis geometry center around a 1,195 mm (47 in) wheelbase engineered for quick, flickable steering geometry. The 4-liter (1.1 US gal) fuel tank paired with a rated consumption of 2.8 L/100 km provides an estimated theoretical range of roughly 143 km (89 miles) between fill-ups, while factory top speed is listed at 50 km/h (31 mph).

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.
Transmission
Transmission and final drive affect maintenance, smoothness and everyday usability.
