The Seattle Supercross could have been the most challenging and treacherous track of the year thus far, as rain in the days before the race softened the dirt surface and left the racers with rutted jump faces, rhythm section transitions, straights, and corners. The action, however, was amazing as home-state hero Levi Kitchen scored a popular win in the 250 Western Regional main and Cooper Webb earned a massively popular victory in the 450 main after a race-long battle with defending Supercross Champion Chase Sexton that saw multiple lead changes.
