Positioned in aeon's scooter motorcycle lineup, the 2014 aeon urban 350i relies on a 313 cc (19.1 cu in) liquid-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 22.8 HP (16.6 kW) at 8,500 rpm while maximum torque reaches 27.3 Nm (20.1 lb-ft) at 5,500 rpm, transferring power to the rear wheel through a automatic gearbox and chain final drive. With a specific output of 72.8 HP per liter and a 3,000 rpm working window between peak torque (5,500 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 urban 350i measures 177 kg (390 lbs) dry, translating to a power-to-weight ratio of 0.13 HP/kg (7.76 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.
