DAYTONA BEACH, Fla. (June 30, 2009) – The AMA Pro Daytona SportBike presented by AMSOIL class is already one of the most diverse divisions in major league motorcycle road racing, but the competition is going to get even more interesting beginning with this weekend’s Red Bull U.S. Grand Prix at Mazda Raceway Laguna Seca. The KTM 990 Super Duke is the 11th different motorcycle approved and homologated for AMA Pro Daytona SportBike competition, and one of the unique twin cylinder bikes will be debuted this weekend at Mazda Raceway. The California-based Tri-Valley Moto team and rider Eric Gulbransen will field the No. 394 KTM 990 Super Duke in Sunday’s AMA Pro Daytona SportBike final. “We have seen outstanding racing this year in AMA Pro Daytona SportBike presented by AMSOIL and that is due to the incredible talent of the teams and riders and the performance of a diverse line-up of motorcycles,” said AMA Pro Racing President Roger Edmondson. “AMA Pro Daytona SportBike is now home to 11 different motorcycles from nine different manufacturers and the parity we have seen in the on-track performance has been unmatched at this level. We welcome KTM and Tri-Valley Moto to the series and know they will be a competitive addition to an already outstanding class.” The Austrian-made KTM brand has been ridden to more than 90 motorcycle championships around the world but the AMA Pro Daytona SportBike debut will be the manufacturer’s first experience in North America at this level. Tri-Valley Moto is based in Livermore, California and Gulbransen is a veteran California rider from Menlo Park, who also has extensive experience racing Ducatis. Dual 23-lap/50-mile sprints for AMA Pro Daytona SportBike and AMA Pro National Guard American Superbike presented by Parts Unlimited will bring the Red Bull U.S. Grand Prix weekend to a close on Sunday, July 5.
