Positioned in aeon's atv motorcycle lineup, the 2009 aeon cobra 50 relies on a 49 cc (3 cu in) air-cooled single cylinder, two-stroke powerplant. In factory specification, peak output is rated at 3.6 HP (2.6 kW) at 5,800 rpm while maximum torque reaches 4.5 Nm (3.3 lb-ft) at 5,700 rpm, transferring power to the rear wheel through shaft drive (cardan) final drive. Internal engine geometry specifies a bore and stroke of 40.0 x 39.2 mm (1.6 x 1.5 inches) with a 6.8:1 compression ratio.
On the scales, the cobra 50 measures 130 kg (287 lbs) dry. Rider ergonomics and chassis geometry center around a 800 mm (31.5 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,050 mm (41.3 in) wheelbase engineered for quick, flickable steering geometry. The 5-liter (1.3 US gal) fuel tank supports practical everyday commuting and weekend road stints.
