Positioned in Qjmotor's custom - cruiser motorcycle lineup, the 2021 Qjmotor QJ250-3B features a 252 cc (15.4 cu in) oil & air-cooled twin, four-stroke configuration. In factory specification, peak output is rated at 17.4 HP (12.7 kW) at 8,000 rpm while maximum torque reaches 16.5 Nm (12.2 lb-ft) at 6,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 69 HP per liter and a 2,000 rpm working window between peak torque (6,000 rpm) and peak power (8,000 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the QJ250-3B measures 166 kg (366 lbs) wet (curb), translating to a power-to-weight ratio of 0.1 HP/kg (9.54 kg per horsepower). Rider ergonomics and chassis geometry center around a 710 mm (28 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,440 mm (56.7 in) wheelbase engineered for balanced agility and highway composure. The 13-liter (3.4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
