2017 Lifan Royal 250 Technical Analysis & Specification Breakdown

At the heart of the 2017 Lifan Royal 250 custom - cruiser motorcycle, Lifan relies on a 248.9 cc (15.2 cu in) air-cooled v2, four-stroke powerplant. In factory specification, peak output is rated at 18.4 HP (13.4 kW) at 8,000 rpm while maximum torque reaches 19 Nm (14 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 73.9 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 Royal 250 measures 152 kg (335 lbs) dry, translating to a power-to-weight ratio of 0.12 HP/kg (8.26 kg per horsepower). Rider ergonomics and chassis geometry center around a 671 mm (26.4 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,494 mm (58.8 in) wheelbase engineered for balanced agility and highway composure. The 14-liter (3.7 US gal) fuel tank paired with a rated consumption of 2.4 L/100 km provides an estimated theoretical range of roughly 583 km (362 miles) between fill-ups, while factory top speed is listed at 121 km/h (75 mph).
