Engineered by Hyosung for the sport touring motorcycle segment, the 2007 Hyosung GT650R TTC utilizes a 647 cc (39.5 cu in) liquid-cooled v2, four-stroke layout. 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 GT650R TTC measures 191 kg (421 lbs) dry, translating to a power-to-weight ratio of 0.4 HP/kg (2.5 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. The 16-liter (4.2 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 210 km/h (130 mph).
