Engineered by Hyosung for the custom - cruiser motorcycle segment, the 2005 Hyosung GV 250 Aquila pairs a 249 cc (15.2 cu in) oil & air-cooled twin, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 26.8 HP (19.6 kW) at 9,200 rpm while maximum torque reaches 21.3 Nm (15.7 lb-ft) at 7,300 rpm, transferring power to the rear wheel through a 5-speed gearbox. With a specific output of 107.6 HP per liter and a 1,900 rpm working window between peak torque (7,300 rpm) and peak power (9,200 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 GV 250 Aquila measures 170 kg (375 lbs) dry, translating to a power-to-weight ratio of 0.16 HP/kg (6.34 kg per horsepower). Rider ergonomics and chassis geometry center around a 700 mm (27.6 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops. The 14-liter (3.7 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 130 km/h (81 mph).
