Built around Aprilia's super motard motorcycle platform, the 2006 Aprilia SXV 5.5 pairs a 549 cc (33.5 cu in) v2, four-stroke architecture with road-focused gearing. Internal engine geometry specifies a bore and stroke of 80.0 x 55.0 mm (3.1 x 2.2 inches) with a 12.0:1 compression ratio.
Rider ergonomics and chassis geometry center around a 918 mm (36.1 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.
Within MotoLibrary's Aprilia archive, this model family spans 7 indexed model years from 2006 to 2013, allowing buyers to track year-over-year changes in emissions tuning, weight and equipment.
