Technical Overview
2017 Hyosung GV650 Pro Technical Analysis & Specification Breakdown
Built around Hyosung's custom - cruiser motorcycle platform, the 2017 Hyosung GV650 Pro features a 647 cc (39.5 cu in) liquid-cooled v2, four-stroke configuration. In factory specification, peak output is rated at 79 HP (57.7 kW) at 9,000 rpm while maximum torque reaches 67 Nm (49.4 lb-ft) at 7,250 rpm, transferring power to the rear wheel through a 5-speed gearbox and belt final drive. With a specific output of 122.1 HP per liter and a 1,750 rpm working window between peak torque (7,250 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 GV650 Pro measures 232 kg (511 lbs) dry, translating to a power-to-weight ratio of 0.34 HP/kg (2.94 kg per horsepower). Rider ergonomics and chassis geometry center around a 690 mm (27.2 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,700 mm (66.9 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.
