Cooper Webb and Tom Vialle 2025 AMA Supercross Champions

Webb Saltk Lake City 25

Red Bull KTM Factory Racing’s Chase Sexton grabbed his seventh win of the season with a statement ride inside Rice-Eccles Stadium at the final round of the 2025 Monster Energy AMA Supercross Championship.

Sexton elected to pull clear of the pack and dominate the race rather than employ tactics in an attempt to impact the points.

Monster Energy Yamaha Star Racing’s Cooper Webb took over the lead on the opening lap but eventually fell back to fourth place in a points preservation ride. Webb’s finish earned him enough points to win the 2025 Monster Energy AMA Supercross Championship and enter the short list of just seven riders who have three or more premier class Supercross titles.

Rockstar Energy Husqvarna Factory Racing’s Malcolm Stewart got the crowd on its feet with a charge from a seventh-place start; Stewart reached the top three positions at the midpoint then broke through to second place in just a few laps. Monster Energy Yamaha Star Racing’s Justin Cooper ran up front throughout the race and wrapped his Supercross season with his third-straight podium finish.

250SX Showdown: Vialle clinch the East title in dramatic fashion

The Dave Coombs Sr. 250SX East/West Showdown became an instant classic for the battle over the Eastern Divisional 250SX Class title which had three riders separated by only three points. When the gate dropped Haiden Deegan rocketed into the lead and ran away with it. Tom Vialle sat in second with the other Eastern Divisional contenders, Monster Energy Pro Circuit Kawasaki’s Seth Hammaker, in fourth, and Rockstar Energy Husqvarna Factory Racing’s RJ Hampshire, in 14th

Along with Western Divisional rider Red Bull KTM Factory Racing’s Julien Beaumer, the four riders threw down for an epic battle that saw several position changes, aggressive passes, and a take-out move that put both Hampshire and Hammaker on the ground. That crash allowed Vialle to slip past and pull the championship back when it had appeared lost. Hammaker made a charge but could not regain the time lost to Vialle. At the checkered flag Deegan cruised to his fourth win, Beaumer took second, and Vialle took third place and secured the 250SX Eastern Divisional Championship.
