2000 Hyosung GF 125 Technical Analysis & Specification Breakdown

Engineered by Hyosung for the naked motorcycle segment, the 2000 Hyosung GF 125 pairs a 124 cc (7.6 cu in) air-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 13.7 HP (10 kW) at 8,600 rpm while maximum torque reaches 11 Nm (8.1 lb-ft) at 7,500 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 110.5 HP per liter and a 1,100 rpm working window between peak torque (7,500 rpm) and peak power (8,600 rpm), the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.

On the scales, the GF 125 measures 126 kg (278 lbs) dry, translating to a power-to-weight ratio of 0.11 HP/kg (9.2 kg per horsepower). Rider ergonomics and chassis geometry center around a 802 mm (31.6 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance.
