Engineered by aeon for the scooter motorcycle segment, the 2012 aeon urban 125 relies on a 124.9 cc (7.6 cu in) liquid-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 14.1 HP (10.3 kW) at 9,000 rpm while maximum torque reaches 11.3 Nm (8.3 lb-ft) at 6,500 rpm, transferring power to the rear wheel through a automatic gearbox and chain final drive. With a specific output of 112.9 HP per liter and a 2,500 rpm working window between peak torque (6,500 rpm) and peak power (9,000 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 urban 125 measures 168 kg (370 lbs) dry, translating to a power-to-weight ratio of 0.08 HP/kg (11.91 kg per horsepower). Rider ergonomics and chassis geometry center around a 815 mm (32.1 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,545 mm (60.8 in) wheelbase engineered for planted straight-line stability. The 13.5-liter (3.6 US gal) fuel tank supports practical everyday commuting and weekend road stints.
