Technical Overview
2012 Aeon My 125i Technical Analysis & Specification Breakdown
Engineered by Aeon for the allround motorcycle segment, the 2012 Aeon My 125i features a 124.9 cc (7.6 cu in) air-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 10.7 HP (7.8 kW) at 8,500 rpm while maximum torque reaches 8.3 Nm (6.1 lb-ft) at 7,500 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 85.7 HP per liter and a 1,000 rpm working window between peak torque (7,500 rpm) and peak power (8,500 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the My 125i measures 108 kg (238 lbs) dry, translating to a power-to-weight ratio of 0.1 HP/kg (10.09 kg per horsepower). Rider ergonomics and chassis geometry center around a 735 mm (28.9 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,210 mm (47.6 in) wheelbase engineered for quick, flickable steering geometry. The 6-liter (1.6 US gal) fuel tank supports practical everyday commuting and weekend road stints.
