450 MAIN

Fans were treated to one of the best 450 main events of the year as four heavy hitters all spent their time at the front of the field. Cooper Webb grabbed the holeshot but Ken Roczen quickly took over the early lead. Roczen held first for the half of the race but struggled once they hit lapped traffic. Once passed, he faded back to fourth.

Aaron Plessinger finished third.

Aaron Plessinger held on for third on the night. The KTM rider won his heat race and used his off-road expertise to hang with the front runners. Once Justin Cooper crashed out of third, Plessinger overtook the position and rounded out the podium.

Cole Davies dominated the 250 main here in Seattle. The Star Racing Yamaha rider grabbed the holeshot and immediately began blitzing the whoops despite the rutted conditions.

Garrett Marchbanks held on for second on the night. The Pro Circuit Kawasaki rider battled for nearly the entire race and fought the ruts and lapped traffic to stay on the box. Marchbanks got away from Beaumer and finished seven seconds behind the leader.
