Built around Hyosung's naked motorcycle platform, the 2008 Hyosung GT650 utilizes a 647 cc (39.5 cu in) liquid-cooled v2, four-stroke layout.
On the scales, the GT650 measures 185 kg (408 lbs) dry. 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. The 17-liter (4.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
Within MotoLibrary's Hyosung archive, this model family spans 7 indexed model years from 2008 to 2017, allowing buyers to track year-over-year changes in emissions tuning, weight and equipment.
