At the heart of the 2008 Aprilia RXV 4.5 enduro - offroad motorcycle, Aprilia utilizes a 449 cc (27.4 cu in) liquid-cooled v2, four-stroke layout. Internal engine geometry specifies a bore and stroke of 76.0 x 49.5 mm (3.0 x 1.9 inches).
Rider ergonomics and chassis geometry center around a 996 mm (39.2 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,495 mm (58.9 in) wheelbase engineered for balanced agility and highway composure. The 7.8-liter (2.1 US gal) fuel tank supports practical everyday commuting and weekend road stints.
