This is the complete and official review of one of the world's leading dirt bike championships. It's packed with high-jumping, mud-flinging action from all 15 rounds of the 2009 World Motocross Championship, with informed commentary guiding fans through the season. There were so many highlights in the 2009 season, we've had to create a 2-disc set to fit it all in. The review includes comprehensive coverage of both the MX1 And MX2 title chases, with both championships providing gripping competition throughout the year. The best footage brings viewers the full story as Antonio Cairoli enjoys a season-long battle with Max Nagl and Clement Desalle before landing his third World Championship with a round to spare and teenager Marvin Musquin fights to the final round in Brazil to claim his first-ever world title.
