Since Tony Cairoli first took a 350 SX-F to the top of the MX1 World Championship in 2010, the Red Bull KTM athlete has dominated the class aboard this nimble but powerful bike with 5 (five!) consecutive world championship titles. No surprises here, with the combination of 450-style muscle and the agility of a 250. Who said you can’t have everything?
