Built around QJmotor's sport motorcycle platform, the 2024 QJmotor SRK550 RS relies on a 554 cc (33.8 cu in) liquid-cooled twin, four-stroke powerplant. In factory specification, peak output is rated at 60.4 HP (44.1 kW) at 8,500 rpm while maximum torque reaches 55 Nm (40.6 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 109 HP per liter and a 2,500 rpm working window between peak torque (6,000 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 SRK550 RS measures 186 kg (410 lbs) wet (curb), translating to a power-to-weight ratio of 0.32 HP/kg (3.08 kg per horsepower). Rider ergonomics and chassis geometry center around a 770 mm (30.3 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,460 mm (57.5 in) wheelbase engineered for balanced agility and highway composure. The 15-liter (4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
