Technical Overview
2009 Lifan Metro 50 Technical Analysis & Specification Breakdown
Positioned in Lifan's scooter motorcycle lineup, the 2009 Lifan Metro 50 relies on a 50 cc (3.1 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 3 HP (2.2 kW) at 7,500 rpm while maximum torque reaches 2.6 Nm (1.9 lb-ft) at 6,000 rpm. With a specific output of 60 HP per liter and a 1,500 rpm working window between peak torque (6,000 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 Metro 50 measures 93.5 kg (206 lbs) dry. Rider ergonomics and chassis geometry center around a 1,250 mm (49.2 in) wheelbase engineered for quick, flickable steering geometry. The 6.4-liter (1.7 US gal) fuel tank paired with a rated consumption of 2.2 L/100 km provides an estimated theoretical range of roughly 291 km (181 miles) between fill-ups.
