Built around Lifan's scooter motorcycle platform, the 2009 Lifan Smart 125 relies on a 119.6 cc (7.3 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 7.5 HP (5.5 kW) at 7,500 rpm while maximum torque reaches 8 Nm (5.9 lb-ft) at 5,500 rpm, transferring power to the rear wheel through a 4-speed gearbox. With a specific output of 62.7 HP per liter and a 2,000 rpm working window between peak torque (5,500 rpm) and peak power (7,500 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 Smart 125 measures 105 kg (231 lbs) dry, translating to a power-to-weight ratio of 0.07 HP/kg (14 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,270 mm (50 in) wheelbase engineered for quick, flickable steering geometry.
