This is the official and action-packed story of one of the most memorable seasons of American MX ever.
We bring you comprehensive highlights from all 12 rounds, from California to Pennsylvania, as the battles for the titles in both the 450 and 250 AMA MX classes go right down to the wire.
There's so much action, we've had to create two discs just to fit it all in!
It was one of the closest fought 450 championships in a decade, with seven different winners, and the competition was just as fierce in 250.
Awesome MX footage brings you the full story as Chad Reed and Ryan Dungey fight to end for class honours.
