Three riders have been selected for each class - 65cc, 85cc and 125cc - to attempt to retain the world championship that the U.S. team won last year in the Czech Republic. It was the U.S. team's third title, following championships in 2011 in Italy and 2010 in France. In 2012 in Bulgaria, the U.S. team finished third.

"We've been working hard to assemble a strong team to represent U.S. motocross in Belgium this summer," said AMA Motocross Manager Kip Bigelow. "Success at this event is a major accomplishment for these young riders, and it gives them incomparable experience as they prepare to launch their professional racing careers. We sincerely appreciate the level at which the riders, their families and the industry support this effort."

This year's 10- to 12-year-old 65cc class team members include Jeremy Ryan from Santa Nella, California, and Carter Biese from Appleton, Wisconsin. Both Ryan and Biese compete on KTM Orange Brigade machines. Also racing in this class will be Monster Energy Kawasaki Team Green rider Jett Reynolds from Bakersfield, California.

Monster Energy Kawasaki Team Green rider Garrett Marchbanks from Coalville, Utah, and KTM Orange Brigade team members Conner Mullennix from Santee, California, and Brock Papi from McMurray, Pennsylvania, will represent the United States in the 11- to 14-year-old 85cc ranks. Mullennix is rejoining the team for the second time in hopes of improving on his 2012 fourth-place finish in the 65cc class in Bulgaria.

"I was so honored to be chosen as a rider for the U.S. team for the FIM Jr. Motocross World Championship," Marchbanks said. "It will be an awesome experience to race against kids from other countries. We hope to bring home the gold!"

In the 13- to 17-year-old 125cc class, FMF Orange Brigade Factory Service KTM team riders Michael Mosiman from Sebastopol, California, and Alexander Frye from Huntingtown, Maryland, will lead the U.S. charge alongside Yamaha-mounted rider Cole Barbieri from Ukiah, California. Both Frye and Barbieri are returning to the team for the second time.

Mosiman is representing the United States for the third time. In 2013, he competed in the 85cc class, laying down the fastest lap time in qualifying.

KTM North America's FMF Orange Brigade KTM Lites Team Manager James Coy will serve as the manager for the U.S. team's FIM Jr. World Championship effort. Coy has worked as a factory mechanic for professional riders such as Travis Pastrana and Ivan Tedesco, and he will surely be instrumental in the success of the team.

The team support crew also includes Jeff Cernic and Josh Mosiman, brother of team rider Michael Mosiman. Cernic, owner of Cernic's Racing and longtime amateur motocross supporter, has an abundance of success on his resume, including supporting Travis Pastrana in his amateur motocross racing days. Mosiman is owner of Super Sketch apparel and a racer himself. He brings four years of experience with the U.S. team, both as a racer and a member of the support crew.

The AMA's Bigelow, also an FIM team jury delegate, said that the team is looking forward to re-creating the success it experienced in 2010, 2011 and 2013.

"Without question, our amateur motocross program in America produces some of the best young racers in the world," Bigelow added. "I'm proud to be a part of this program and to be able to help provide the riders and the families with this exceptional experience."
