Carlo Caresana — Provincia Pavia, Italy

Carlo first stepped onto a dirt bike at age 6. Soon after, his father built him his very own track in the family's backyard. Call it a competitive advantage: By the time he was 18, he was winning rookie and expert regional motocross championships. But then he started hitting metal ramps, and this was when he learned that his true motocross calling was freestyle. (Photo: Ricky Monti)
