Built around Hyosung's custom - cruiser motorcycle platform, the 2005 Hyosung GV 125 Aquila utilizes a 125 cc (7.6 cu in) twin, four-stroke layout. In factory specification, peak output is rated at 14.8 HP (10.8 kW) at 10,300 rpm while maximum torque reaches 10 Nm (7.4 lb-ft) at 10,000 rpm. With a specific output of 118.4 HP per liter and a 300 rpm working window between peak torque (10,000 rpm) and peak power (10,300 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 125 Aquila measures 163 kg (359 lbs) dry, translating to a power-to-weight ratio of 0.09 HP/kg (11.01 kg per horsepower). Rider ergonomics and chassis geometry center around a 665 mm (26.2 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 110 km/h (68 mph).
