Built around aeon's scooter motorcycle platform, the 2012 aeon quadro 350d utilizes a 313 cc (19.1 cu in) liquid-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 22.8 HP (16.6 kW) at 7,000 rpm while maximum torque reaches 23.7 Nm (17.5 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 72.8 HP per liter and a 1,000 rpm working window between peak torque (6,000 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 quadro 350d measures 200 kg (441 lbs) dry, translating to a power-to-weight ratio of 0.11 HP/kg (8.77 kg per horsepower). Rider ergonomics and chassis geometry center around a 780 mm (30.7 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance. The 13-liter (3.4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
