So who can we expect to see up front on Sunday? "The trio of Marvin Musquin, Jeffrey Herlings and Ken Roczen is going to be cool to see in MX2, but the real battle will be watching Tony Cairoli try to defend his #1 plate in the MX1 class. Musquin and Roczen will be tough to beat, even for the Americans and I hope some top U.S. guys will join the party in Glen Helen," says DV12. "In MX1, Cairoli is the guy to beat on the new KTM 350, but there are a lot of great riders. Clement DeSalle from France, David Philipaerts from Italy, Max Nagl from Germany... I can't wait to see those guys race each other!"
