At the heart of the 2021 Qjmotor QJ500-11A allround motorcycle, Qjmotor pairs a 500 cc (30.5 cu in) liquid-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 25.5 HP (18.6 kW) at 5,500 rpm while maximum torque reaches 40 Nm (29.5 lb-ft) at 4,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 51 HP per liter and a 1,500 rpm working window between peak torque (4,000 rpm) and peak power (5,500 rpm), the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the QJ500-11A measures 198 kg (437 lbs) wet (curb), translating to a power-to-weight ratio of 0.13 HP/kg (7.76 kg per horsepower). Rider ergonomics and chassis geometry center around a 700 mm (27.6 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,580 mm (62.2 in) wheelbase engineered for planted straight-line stability. The 15.5-liter (4.1 US gal) fuel tank supports practical everyday commuting and weekend road stints.
