2017 Loncin GP250 Technical Analysis & Specification Breakdown

Built around Loncin's sport motorcycle platform, the 2017 Loncin GP250 pairs a 223 cc (13.6 cu in) oil & air-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 17.7 HP (12.9 kW) at 8,500 rpm while maximum torque reaches 17.2 Nm (12.7 lb-ft) at 6,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 79.4 HP per liter and a 2,500 rpm working window between peak torque (6,000 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 GP250 measures 125 kg (276 lbs) dry, translating to a power-to-weight ratio of 0.14 HP/kg (7.06 kg per horsepower). Rider ergonomics and chassis geometry center around a 780 mm (30.7 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,335 mm (52.6 in) wheelbase engineered for quick, flickable steering geometry. The 12-liter (3.2 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 105 km/h (65 mph).
