Team Yoshimura Suzuki’s Ben Spies raced his GSX-R1000 to a second consecutive AMA Superbike Championship double-header victory at the second Fontana race in California. The 23-year-old Texan took the lead from the start from team mate Mat Mladin, lost it, then moved to the front again to win by 4.4 seconds over the six-time champion. Aaron Yates, who finished third in the Superstock race earlier in the day, finished eighth overall.
