Technical Overview
2019 Aeon 3D-350 R Technical Analysis & Specification Breakdown
Positioned in Aeon's scooter motorcycle lineup, the 2019 Aeon 3D-350 R relies on a 346 cc (21.1 cu in) liquid-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 30 HP (21.9 kW) at 7,500 rpm while maximum torque reaches 30 Nm (22.1 lb-ft) at 6,000 rpm, transferring power to the rear wheel through a automatic gearbox and chain final drive. With a specific output of 86.7 HP per liter and a 1,500 rpm working window between peak torque (6,000 rpm) and peak power (7,500 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 3D-350 R measures 224 kg (494 lbs) dry, translating to a power-to-weight ratio of 0.13 HP/kg (7.47 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.
