2013 Aprilia SXV 5.5

2013 Aprilia SXV 5.5 sits as the bigger-engined half of Aprilia's oddball supermoto pairing, built for riders who want dirt-bike aggression with pavement manners. This is a road-legal machine wearing a motocross skeleton, powered by a V-twin that was originally engineered for off-road competition rather than street commuting. That heritage shows in how it rides: it's light, it revs hard, it wants to be flicked from side to side rather than cruised, and the titanium valve hardware in the head hints at the weight-obsessed engineering that went into the whole project. It's not a bike that flatters lazy riding — you have to be somewhat committed to get the best from it. The 2013 model carried over without significant mechanical changes from the prior year — buyers comparing it to a 2012 example should focus on mileage, service history, and condition rather than spec differences. Given how few of these Aprilia built and how maintenance-intensive the V-twin can be, most 2013 SXV 5.5 buyers are experienced riders coming from motocross or supermoto backgrounds who want something genuinely different from a mainstream Japanese street bike, and who don't mind chasing parts or working with an independent specialist to keep it running right.
