Engineered by Hyosung for the custom - cruiser motorcycle segment, the 2006 Hyosung Aquila 125 features a 125 cc (7.6 cu in) oil & air-cooled twin, four-stroke configuration. In factory specification, peak output is rated at 14.8 HP (10.8 kW) at 10,500 rpm while maximum torque reaches 9.7 Nm (7.2 lb-ft) at 10,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 118.4 HP per liter and a 500 rpm working window between peak torque (10,000 rpm) and peak power (10,500 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 Aquila 125 measures 161 kg (355 lbs) wet (curb), translating to a power-to-weight ratio of 0.09 HP/kg (10.88 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 100 km/h (62 mph).
