May 20, 2010 - Glen Helen Raceway, CA - Just in from Youthstream, promoters of the FIM World Motocross Championship is the confirmed rider list of the top European stars set to race the forthcoming USGP at Glen Helen on May 30th. Headed by defending MX1 champion Team Red Bull KTM's Antonio Cairoli and his wingman, Germany's Max Nagl, the talent pool is filled with the best MX racers in the world.

"Although American fans may not know all the names, guys like Cairoli and Nagl are really good," says former GP racer and 2-time World Champion Sebastien Tortelli. In fact, Cairoli and Nagl are currently flying 1-2 in the premiere MX1 class after five GP races in Europe this season. "And in MX2, watch for another Team Red Bull KTM rider Marvin Musquin to dice with Jefferey Herlings and Team Teka Suzuki's Ken Roczen. Musquin and Roczen will be tough to beat," says Seb, who is about ready to embark on a series of MX Training camps across the country this summer www.champfactory.com. "But before I go anywhere, I'm planning on watching the USGP at Glen Helen!"
