Built around Hyosung's custom - cruiser motorcycle platform, the 2001 Hyosung Aquila 125 relies on a 125 cc (7.6 cu in) v2, four-stroke powerplant. In factory specification, peak output is rated at 14.5 HP (10.6 kW) at 10,300 rpm while maximum torque reaches 12.5 Nm (9.2 lb-ft) at 8,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 116 HP per liter and a 2,300 rpm working window between peak torque (8,000 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 Aquila 125 measures 140 kg (309 lbs) dry, translating to a power-to-weight ratio of 0.1 HP/kg (9.66 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 1,490 mm (58.7 in) wheelbase engineered for balanced agility and highway composure. The 14.5-liter (3.8 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 105 km/h (65 mph).
