The first corner swallowed up a handful of riders at the start of the 450SX main event, including top riders such as Ryan Villopoto, Ken Roczen, James Stewart, Dean Wilson and a few more. Alessi was able to pull through with the holeshot, and Ryan Dungey and Eli Tomac were right there behind him. Justin Brayton and Cole Seely followed them up in fourth and fifth.
Dungey pulled into the lead and past Alessi by drag racing him into the corner following the steep wall jump. Tomac challenged Alessi but eventually fell off the pace, but Alessi gave up second after a nasty crash. Villopoto and Roczen had moved into the top ten, but Roczen crashed out after experiencing a nasty crash as well.
Villopoto was able to move up to fourth, but wasn’t able to catch Seely for the podium position. Tickle followed up Villopoto in fifth for an excellent ride. Tomac held onto second place—his first 450SX podium ever—and Dungey rode a very consistent race and on to his first 450SX win of the season.
Vince Friese was able to get the holeshot over Martin Davalos by a knobby in the 250SX main event. Adam Cianciarulo was right there in third, and both he and Davalos were able to get by Friese through the second turn. Jimmy Decotis and Matt Bisceglia rounded out the top five early in the race.
Bisceglia was able to move past Decotis and Friese into third after the opening lap. Friese fell back to fifth, allowing Decotis to hold down fourth for quite some time. Meanwhile, Davalos dropped his bike and gave up the lead to Cianciarulo—and second to Bisceglia—after losing the back wheel on the exposed plywood flooring. Cianciarulo low-sided exactly one lap later in a low-speed corner, but was able to pick his bike quick enough to keep the lead.
Justin Bogle made his way up to fourth halfway through the race after a poor start. Both Davalos and Bogle were able to move past Bisceglia to finish in podium positions, while Cianciarulo went on to win his second race of the season.
