It all comes down to this! Welcome to Salt Lake City for round 17 of the 2025 Monster Energy AMA Supercross series. Tonight will decide this year’s 450SX champion along with the 250SX East Coast crown. The East/West Showdown will also bring another factor into tonight’s racing. At the end of a wild night, Chase Sexton and Haiden won their respective main events, while Cooper Webb and Tom Vialle clinched the overall titles.
450 MAIN EVENT
The final 450SX main event kicked off with Aaron Plessinger grabbing the holeshot. The KTM rider started up front but quickly dropped to second as Cooper Webb made a move to the lead on lap one.
Webb showed some serious speed in the opening laps but only needed to finish fifth or better to take the title. Chase Sexton followed Webb to the front of the field and gave chase to the points leader before ultimately making a pass for the lead.
Once Sexton took the lead, he rode away from the rest of the podium contenders and claimed the win by more than 10 seconds. Despite winning the finale he finished second in the season standings.
Malcolm Stewart fought his way to second at the checkers. The Rockstar Husqvarna rider needed every position to maximize his points in the overall championship as he was fighting with Justin Cooper in the season standings. Stewart got around Cooper Webb and Justin Cooper in the closing stages of the race and finished just one spot behind his season-best result. He still took fourth in the overall points, four points behind Cooper.
Justin Cooper rounded out the podium with a third on the night. The Star Racing Yamaha rider worked his way into third and ran most of the race behind his teammate Webb. Webb eventually gave way to Cooper and the #32 moved to second but Stewart was on a charge in the final laps. Cooper had extra points to play with and even with Stewart’s pass he would hold third in the championship standings.
Cooper Webb crossed the line in fourth after leading early on. He needed fifth or better to clinch the title and fans could see noticeable drop in Webb’s pace once Cooper and Stewart made their way around. A safe fourth earned him a third championship, winning the war at the end of the season.

250SX MAIN EVENT
The 250SX Showdown was all about Haiden Deegan. The newly crowned West Coast champ led every lap of the season finale and dominated the field by more than 10 seconds. He ends the season on a high note as the fastest 250 rider.
Julien Beaumer crossed the line second in the main event. The Red Bull KTM rider pushed up to the back of his teammate Tom Vialle and looked to be helping his fellow KTM rider defend against the championship. Beaumer eventually made his way around Vialle and later traded paint with Seth Hammaker in the mid-section of the race. Beaumer later dropped back to fourth as Hammaker and Hampshire duked it out, but he regained both spots as the dueling duo ended up on the ground. Beaumer took second on the night and jumped to second in the West Coast points with Cole Davies not racing tonight.
Tom Vialle finished third claimed his second-consecutive East Coast title in the process. The KTM rider started up front in second but faded back as the laps wore on. Once his teammate Beaumer got around, Vialle dropped back in position. Hammaker and Hampshire both found their way past the 1E and the title quickly seemed out of reach.
Hammaker led the charge but Hampshire knocked down a massive gap and followed the Kawasaki rider into podium position. Hampshire went for a daring pass just before the finish and put both contenders on the ground. This move allowed Beaumer and Vialle to slip back by, putting the title back in Vialle’s hands.
Hammaker remounted and made a late-race charge but couldn’t re-pass Vialle. Hampshire crossed the line back in sixth.

With the 250SX West title already clinched by Haiden Deegan, the pressure is off in terms of the overall championship.

Deegan was still second in the West session, just three-tenths off of Beaumer’s pace. Cole Davies’ time from Q1 still held up for third overall despite not riding the second session.
Seth Hammaker is making his intentions clear as he set the best time in the 250SX East division. It will be a winner take all race tonight as Hammaker, Hampshire, and Vialle are all within three points of each other. Hampshire and Vialle rounded out the top three, all within half a second.
A big incident came in the first West qualifying session as Jordon Smith crash landed onto Cole Davies. The session was red flagged as both riders exited the track. Davies was transported to the local hospital with an arm injury while Smith will make a game time decision for the main event.
