Technical Overview
2024 Aeon Cobra 400 SM Technical Analysis & Specification Breakdown
Built around Aeon's atv motorcycle platform, the 2024 Aeon Cobra 400 SM features a 346 cc (21.1 cu in) liquid-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 20.1 HP (14.7 kW) at 6,500 rpm while maximum torque reaches 23.4 Nm (17.3 lb-ft) at 3,500 rpm, transferring power to the rear wheel through a automatic gearbox and chain final drive. With a specific output of 58.1 HP per liter and a 3,000 rpm working window between peak torque (3,500 rpm) and peak power (6,500 rpm), the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the Cobra 400 SM measures 215 kg (474 lbs) dry, translating to a power-to-weight ratio of 0.09 HP/kg (10.7 kg per horsepower). Rider ergonomics and chassis geometry center around a 829 mm (32.6 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,300 mm (51.2 in) wheelbase engineered for quick, flickable steering geometry. The 9.3-liter (2.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
