Positioned in Aprilia's scooter motorcycle lineup, the 2005 Aprilia Atlantic 500 utilizes a 460 cc (28.1 cu in) liquid-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 29 HP (21.2 kW) at 7,250 rpm while maximum torque reaches 40 Nm (29.5 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 63 HP per liter and a 1,750 rpm working window between peak torque (5,500 rpm) and peak power (7,250 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
Rider ergonomics and chassis geometry center around a 678 mm (26.7 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 770 mm (30.3 in) wheelbase engineered for quick, flickable steering geometry.
Within MotoLibrary's Aprilia archive, this model family spans 2 indexed model years from 2004 to 2005, allowing buyers to track year-over-year changes in emissions tuning, weight and equipment.
