2025 Philadelphia Supercross 450 Main Event | Ground Level

The 450 Main Event at the 2025 Philadelphia Supercross was another bout between Chase Sexton and Cooper Webb.

The 25-lap feature saw the title contenders caught up in the chaos of the first turn, race back to first and second with seemingly synchronized passes, and keep within five seconds of each other during the final fast push while navigating slower traffic and the technical track.

Sexton's fourth victory cut Webb's advantage in the championship standings to 12 points, a narrow margin with four rounds remaining in the Monster Energy Supercross Championship.
