Engineered by Lifan for the sport motorcycle segment, the 2012 Lifan LF125-9A utilizes a 124 cc (7.6 cu in) liquid-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 11.4 HP (8.3 kW) at 8,500 rpm while maximum torque reaches 9.5 Nm (7 lb-ft) at 7,500 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 91.9 HP per liter and a 1,000 rpm working window between peak torque (7,500 rpm) and peak power (8,500 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 LF125-9A measures 108 kg (238 lbs) dry, translating to a power-to-weight ratio of 0.11 HP/kg (9.47 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 1,290 mm (50.8 in) wheelbase engineered for quick, flickable steering geometry. The 10.5-liter (2.8 US gal) fuel tank paired with a rated consumption of 2.1 L/100 km provides an estimated theoretical range of roughly 500 km (311 miles) between fill-ups, while factory top speed is listed at 90 km/h (56 mph).
