At the start of the 450cc main event, it was San Manuel Yamaha’s Stewart with the lead, followed closely, of course, by Rockstar/Makita Suzuki’s Mike Alessi. Alessi quickly lost a spot to Yamaha’s Broc Hepler, and then Monster Energy Kawasaki’s Ryan Villopoto and Honda Red Bull Racing’s Davi Millsaps. Reed rounded lap one sixth after passing a few riders on the opening circuit.
Stewart immediately began pulling away from Hepler, who quickly found Villopoto and Reed breathing down his neck. Finally, on lap nine of 20, Hepler was passed by both of them, and Reed set out after Villopoo while Hepler struggled with maintaining the top-rider pace for 20 laps in only his second race back.
Reed passed Villopoto for second only a couple of laps later, only to lose the spot back to Villopoto when he was balked by lapped rider Troy Adams, who got up trying to get out of the way, but moved directly into the way instead.
Monster Energy/Pro Circuit Kawasaki teammates Austin Stroupe and Christophe Pourcel went 1-2 off the start of the Lites main event, and Stroupe began to pull away from Pourcel after a few laps, but at the beginning of the 10th circuit (of 15), Stroupe stalled his motorcycle and couldn’t get it restarted. He got going again in eighth, while Pourcel assumed the lead.
Rockstar/Makita Suzuki’s Nico Izzi caught up to second, followed by Division 7/Star Racing Yamaha’s Matt Lemoine, Muscle Milk/MDK KTM’s Martin Davalos, Canidae/Motosport Kawasaki’s Branden Jesseman, and GEICO Powersports Honda’s Blake Wharton.
With Pourcel out of reach for Izzi, Izzi settled for second, while eventually the battle for third became heated between Wharton (coming from the back) and Davalos. Wharton made the pass on Davalos, but then on the last lap, Davalos block-passed Wharton with only a couple of turns to go to take the final podium spot. Wharton was fourth, Jesseman was fifth, Wil Hahn was sixth, and Stroupe was seventh.
