At the heart of the 2025 Lifan KPmini RS minibike, sport motorcycle, Lifan features a 149 cc (9.1 cu in) air-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 13 HP (9.5 kW) at 8,000 rpm while maximum torque reaches 12 Nm (8.9 lb-ft) at 6,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 87.2 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 KPmini RS measures 110 kg (243 lbs) dry, translating to a power-to-weight ratio of 0.12 HP/kg (8.46 kg per horsepower). Rider ergonomics and chassis geometry center around a 730 mm (28.7 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,220 mm (48 in) wheelbase engineered for quick, flickable steering geometry. The 5.5-liter (1.5 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 105 km/h (65 mph).
