Built around Hyosung's sport motorcycle platform, the 2010 Hyosung GT650R utilizes a 647 cc (39.5 cu in) liquid-cooled v2, four-stroke layout. Internal engine geometry specifies a bore and stroke of 81.5 x 62.0 mm (3.2 x 2.4 inches) with a 11.6:1 compression ratio.
On the scales, the GT650R measures 215 kg (474 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 831 mm (32.7 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,435 mm (56.5 in) wheelbase engineered for balanced agility and highway composure. The 17.03-liter (4.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
