Built around aeon's atv motorcycle platform, the 2009 aeon cobra 320 utilizes a 272.3 cc (16.6 cu in) liquid-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 19.4 HP (14.2 kW) at 6,500 rpm while maximum torque reaches 19 Nm (14 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 71.2 HP per liter and a 1,000 rpm working window between peak torque (5,500 rpm) and peak power (6,500 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 cobra 320 measures 50 kg (110 lbs) wet (curb), translating to a power-to-weight ratio of 0.39 HP/kg (2.58 kg per horsepower). Rider ergonomics and chassis geometry center around a 790 mm (31.1 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,300 mm (51.2 in) wheelbase engineered for quick, flickable steering geometry. The 7.3-liter (1.9 US gal) fuel tank supports practical everyday commuting and weekend road stints.
