The big bikes got everyone's attention quick as the first corner saw Byrne going in first but with Carmichael and Tedesco both cutting under on the inside. The three riders exited the sweeping first turn three abreast, with Ricky pulling the lead through the whoops. Ricky's lead lasted just until the next corner, where Byrne ducked under him on the berm and retook the lead. Ricky gave right back, and before Byrne had time to take a breath Ricky had reclaimed the lead. Ricky had had enough excitement for the heat and quickly pulled a gap on Byrne. Tedesco started the attack from behind, and overtook Byrne with an aggressive inside move on lap three. Byrne looked sure to be coming under attack by Windham next, who was absolutely flying through the whoops. But Byrne was perfect and quick through the whoops himself, and Windham could not close the gap between them. Byrne actually pulled Windham just a bit before the heat was over. The riders going straight to the main were Carmichael, Tedesco, Byrne, Windham, and Danny Smith.
Heat two had just as much speed, but a lot less drama - at least up front. James Stewart grabbed the holeshot and spent the heat alone out front. Stewart was cutting some unique lines squaring off some of the berms and looking great. Vuillemin advanced from third to second in the second corner and kept Stewart honest by never letting him pull much of a gap after the first couple of lap. The excitement in this heat was found back in fifth, where Chad Johnson was all over Cole Siebler. Finally on the eighth of ten laps, Johnson cut inside and made contact in a berm. Siebler got the worst of it as he was pushed into a tuff block and went down. He kept the motor running but lost three positions in the crash. The final finishing order was Stewart, Vuillemin, Tim Ferry, Chad Johnson, and Kyle Partridge.
Sean Hackley grabbed the holeshot in the lites LCQ, but Tommy Hahn blitzed through the whoops right after the first turn and grabbed the lead. Hahn would never give it up and rode smoothly to the LCQ win. Hackley would hold second, despite a last minute charge from Matt Goerke. Goerke charged through the rhythm section before the final corner and could have put a bad t-bone move on Hackley, but Goerke slowed and made a more gentle contact to Hackley's rear wheel. Hackley stayed up and held on for the last transfer to the main.
The Supercross LCQ was an thrilling one. Cole Siebler got the holeshot and the worst seat in the house as all the excitement was taking place behind him in the battle for second place - the last transfer into the main. Heath Voss started the LCQ in fifth, but blazed past Jason Thomas in the whoops on lap two of the six lap race. Voss has a unique, and fast, step-on step-off line over the finish line tabletop. On lap four he stepped off, jumping nearly into the corner where he rounded the berm side by side with Kevin Johnson, who was holding third. The two riders jumped side by side over a small double and into a tight turn, where Johnson held the inside. Voss tried to square up and cut under, but Johnson anticipated it and slowed. Voss had no room to pass under, so he accelerated around, but Johnson had him covered as the two raced out of the arena.
On the fifth lap, Johnson passed Brock Sellards for second in the corner after the whoops. Voss got around Sellards in the very next corner with a close move that pushed Sellards wide. The battle between Voss and Johnson continued, now for the final ticket into the main event.
