2007 Hyosung GT650S Sport - Comet 650 S Technical Analysis & Specification Breakdown

Engineered by Hyosung for the sport motorcycle segment, the 2007 Hyosung GT650S Sport - Comet 650 S pairs a 647 cc (39.5 cu in) liquid-cooled v2, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 76.4 HP (55.8 kW) at 9,000 rpm while maximum torque reaches 68 Nm (50.2 lb-ft) at 7,000 rpm, transferring power to the rear wheel through a 6-speed gearbox. With a specific output of 118.1 HP per liter and a 2,000 rpm working window between peak torque (7,000 rpm) and peak power (9,000 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 GT650S Sport - Comet 650 S measures 189 kg (417 lbs) dry, translating to a power-to-weight ratio of 0.4 HP/kg (2.47 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 1,435 mm (56.5 in) wheelbase engineered for balanced agility and highway composure.
