Built around Qjmotor's naked motorcycle platform, the 2021 Qjmotor QJ500GS-5F pairs a 502 cc (30.6 cu in) liquid-cooled twin, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 48.3 HP (35.2 kW) at 8,500 rpm while maximum torque reaches 47 Nm (34.7 lb-ft) at 5,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 96.2 HP per liter and a 3,500 rpm working window between peak torque (5,000 rpm) and peak power (8,500 rpm), the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.
On the scales, the QJ500GS-5F measures 225 kg (496 lbs) wet (curb), translating to a power-to-weight ratio of 0.21 HP/kg (4.66 kg per horsepower). Rider ergonomics and chassis geometry center around a 825 mm (32.5 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,500 mm (59.1 in) wheelbase engineered for balanced agility and highway composure. The 19.5-liter (5.2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
