Built around aeon's prototype - concept model motorcycle platform, the 2008 aeon cobra 320 relies on a 272.3 cc (16.6 cu in) single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 18.8 HP (13.7 kW) at 6,500 rpm while maximum torque reaches 22 Nm (16.2 lb-ft) at 5,500 rpm. With a specific output of 69 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 206 kg (454 lbs) dry, translating to a power-to-weight ratio of 0.09 HP/kg (10.96 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 8.5-liter (2.2 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 82 km/h (51 mph).
