Since the untimely departure of GEICO Honda's Eli Tomac from the championship as a result of injury, Dungey and defending champion Ken Roczen, who rides for RCH Soaring Eagle/Jimmy Johns/Suzuki Factory Racing, have dominated the 450 Class and, in turn, have opened a considerable gap over the rest of the field in the championship standings. However, the unpredictable conditions at Budds Creek opened the door for another rider to emerge at the forefront of the division. A native of New York, Barcia is arguably more comfortable in the wet than perhaps any other rider in the series and thrived all afternoon. While Dungey took a convincing win in Moto 1, he had a big crash off the start of Moto 2 and was left to fight his way through the field when conditions were at their worst. Barcia, who had grabbed the holeshot, took full advantage and cruised to his maiden victory both in the premier class and for the Joe Gibbs Racing Motocross effort who signed him for the 2015 season and earned just its second win in its eighth season of competition.
