2010 Aprilia MXV 4.5
The competition-only Aprilia MXV 4.5 might be the most memorable machine your fellow racers have ever had the displeasure of seeing pulling away. It’s not only the world’s only V-twin motocross bike, it’s the most exotic ride lined up at the gate. With the ability to convert the engine from a big bang to a screamer the MXV provides owners a unique experience. Authentic Italian style and world-class technology make the MXV an exclusive choice for amateur or pro motocrossers who are tired of the same-old choices in competition-caliber machines. The under-seat exhaust configuration gives racers even more torque at lower revs.
