2019 Aeon 3D-350 Technical Analysis & Specification Breakdown

At the heart of the 2019 Aeon 3D-350 scooter motorcycle, Aeon relies on a 346 cc (21.1 cu in) liquid-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 27 HP (19.7 kW) at 7,000 rpm while maximum torque reaches 28.8 Nm (21.2 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 78 HP per liter and a 1,500 rpm working window between peak torque (5,500 rpm) and peak power (7,000 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 3D-350 measures 212.5 kg (468 lbs) dry, translating to a power-to-weight ratio of 0.13 HP/kg (7.87 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 1,565 mm (61.6 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.
