Engineered by Hyosung for the custom - cruiser motorcycle segment, the 2009 Hyosung GV 650 EFI relies on a 647 cc (39.5 cu in) liquid-cooled v2, four-stroke powerplant. In factory specification, peak output is rated at 80 HP (58.4 kW) at 9,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and belt final drive. With a specific output of 123.6 HP per liter, 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 GV 650 EFI measures 218 kg (481 lbs) dry, translating to a power-to-weight ratio of 0.37 HP/kg (2.73 kg per horsepower). Rider ergonomics and chassis geometry center around a 705 mm (27.8 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,665 mm (65.6 in) wheelbase engineered for planted straight-line stability. The 16-liter (4.2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
