LF400 V Twin

2009 Lifan LF400 V Twin Technical Analysis & Specification Breakdown

Built around Lifan's custom - cruiser motorcycle platform, the 2009 Lifan LF400 V Twin utilizes a 399 cc (24.4 cu in) air-cooled v2, four-stroke layout. In factory specification, peak output is rated at 26.8 HP (19.6 kW) at 8,500 rpm while maximum torque reaches 22 Nm (16.2 lb-ft) at 7,000 rpm, transferring power to the rear wheel through a 5-speed gearbox. With a specific output of 67.2 HP per liter and a 1,500 rpm working window between peak torque (7,000 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 LF400 V Twin measures 175 kg (386 lbs) dry, translating to a power-to-weight ratio of 0.15 HP/kg (6.53 kg per horsepower). Rider ergonomics and chassis geometry center around a 720 mm (28.3 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,540 mm (60.6 in) wheelbase engineered for planted straight-line stability. The 13.5-liter (3.6 US gal) fuel tank paired with a rated consumption of 3.2 L/100 km provides an estimated theoretical range of roughly 422 km (262 miles) between fill-ups, while factory top speed is listed at 120 km/h (75 mph).
