Film/Text: Red Bull

With Zach Osborne out with a shoulder injury, TLD riders Shane McElrath and Alex Martin attempt to chase down red plate holder Aaron Plessinger in the 250 Class at the notorious Southwick Raceway. In the 450 Class, Red Bull KTM's Marvin Musquin enters "Americas Track," Red Bud Raceway with over a 30-point deficit, and what happens on that Fourth of July weekend confirms the common motocross phrase, "anything can happen when the gate drops.”

The motocross series “MX Nation” is once again lifting the curtain to peek behind the scenes of the Lucas Oil Pro Motocross Championship. Behind the speed, the trophies, and the fame lies hard work, sacrifice, and struggle. Follow the racers as they challenge each other and themselves for racing glory. What happens on race day is only a fraction of the battle. This is MX Nation.
