Each year riders from around the world seek to prove they have the talent, focus and confidence required to be named the next Motocross Champion.
Ken Roczen, the German-born returning champion, strives to capture the prestigious title for the second time in a row with the support of his new race team RCH, but his coming off of a disastrous Supercross season plagued by injuries has placed doubt in the minds of many.
His former team-mate, Ryan Dungey, seems to be at the height of his racing career and more determined than ever to take back the championship title which was once his in 2012.
Over the course of six episodes, this series follows Roczen, Dungey and others throughout the 2015 Motocross season as they endure the unending pain of preparation, weekly travel throughout the United States and the expectations of fathers, fans, sponsors and internal demons.
