2013 Aprilia SXV 4.5

2013 Aprilia SXV 4.5 sits in the middle of Aprilia's supermoto range, a step up from the SX 50 and a notch below the more aggressive SXV 5.5. This is a road-legal machine built around a motocross-derived V-twin, which means it carries none of the flywheel weight or soft power delivery you'd expect from a typical street bike. It's light, it revs with urgency, and it wants a rider who's comfortable pushing hard through corners rather than cruising boulevards. Owning one means accepting a stiff maintenance rhythm — valve checks, careful attention to the wet-liner cylinders, and a bike that punishes neglect rather than tolerating 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.

The typical 2013 Aprilia SXV 4.5 buyer is someone coming from dirt bikes or track days who wants that same razor-edged responsiveness with a plate on it. It's not a commuter, and it's not chasing collector money yet. It appeals to riders who want a demanding, engaged riding experience over comfort or convenience.
