Built around Lifan's scooter motorcycle platform, the 2020 Lifan BWS125 pairs a 124.6 cc (7.6 cu in) air-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 8.1 HP (5.9 kW) at 7,000 rpm while maximum torque reaches 7.5 Nm (5.5 lb-ft) at 6,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and belt final drive. With a specific output of 65 HP per liter and a 1,000 rpm working window between peak torque (6,000 rpm) and peak power (7,000 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 BWS125 measures 115 kg (254 lbs) dry, translating to a power-to-weight ratio of 0.07 HP/kg (14.2 kg per horsepower). Rider ergonomics and chassis geometry center around a 790 mm (31.1 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,330 mm (52.4 in) wheelbase engineered for quick, flickable steering geometry. The 5.5-liter (1.5 US gal) fuel tank paired with a rated consumption of 2.5 L/100 km provides an estimated theoretical range of roughly 220 km (137 miles) between fill-ups, while factory top speed is listed at 85 km/h (53 mph).

Torque
Torque is useful for judging real-world pull, especially for touring, commuting and loaded riding.
Seat Height
Check the seat height against your inseam and riding posture before choosing a motorcycle.
Weight
Compare weight carefully because it affects low-speed handling, parking and confidence.
Fuel Capacity
Fuel capacity helps estimate touring range and how often you may need to stop.
Brakes
Brake setup is worth comparing if you ride in traffic, mountains or with a passenger.
Transmission
Transmission and final drive affect maintenance, smoothness and everyday usability.
