2011 Hyosung GT125R Technical Analysis & Specification Breakdown

Positioned in Hyosung's sport motorcycle lineup, the 2011 Hyosung GT125R pairs a 125 cc (7.6 cu in) oil & air-cooled v2, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 14.2 HP (10.4 kW) at 10,500 rpm while maximum torque reaches 10.2 Nm (7.5 lb-ft) at 9,750 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 113.6 HP per liter and a 750 rpm working window between peak torque (9,750 rpm) and peak power (10,500 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 GT125R measures 166 kg (366 lbs) dry, translating to a power-to-weight ratio of 0.09 HP/kg (11.69 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 1,445 mm (56.9 in) wheelbase engineered for balanced agility and highway composure. The 17-liter (4.5 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 110 km/h (68 mph).
