At the heart of the 2006 Hyosung Aquila 250 custom - cruiser motorcycle, Hyosung features a 250 cc (15.3 cu in) oil & air-cooled twin, four-stroke configuration. In factory specification, peak output is rated at 28.2 HP (20.6 kW) at 10,000 rpm while maximum torque reaches 22 Nm (16.2 lb-ft) at 7,300 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 112.8 HP per liter and a 2,700 rpm working window between peak torque (7,300 rpm) and peak power (10,000 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 Aquila 250 measures 166 kg (366 lbs) dry, translating to a power-to-weight ratio of 0.17 HP/kg (5.89 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).
