Built around Aprilia's scooter motorcycle platform, the 2006 Aprilia Atlantic 250 relies on a 244 cc (14.9 cu in) liquid-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 20.1 HP (14.7 kW) at 6,250 rpm while maximum torque reaches 20.2 Nm (14.9 lb-ft) at 6,800 rpm, transferring power to the rear wheel through belt final drive. With a specific output of 82.4 HP per liter, 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 1,470 mm (57.9 in) wheelbase engineered for balanced agility and highway composure. The 10.5-liter (2.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
