The initial idea was to line up in the MX1 World Championship with a bike featuring reduced displacement, but all the advantages of a lighter bike. The final result was the birth of the 350 SX-F and foundations being laid for a legend. Its first victory in the first race for Toni Cairoli, and the world championship title in its first season - what better proof could there be for the brilliance of this concept? The sensation of the 2010 MX season enters the next round with a revamped chassis.
