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.
In the Dave Coombs Sr. 250SX East/West Showdown, Monster Energy Yamaha Star Racing’s Haiden Deegan grabbed the holeshot and was never challenged for the lead; this backs up his win the week before when he wrapped up the Western Divisional 250SX Class Championship. Behind Deegan, the three-rider fight for the Eastern Divisional 250SX Class Championship was settled with a wildly dramatic battle that saw Red Bull KTM Factory Racing’s Tom Vialle finish in third place to earn a consecutive Eastern Divisional 250SX Class title.
“A little bit too late, obviously. Cooper had an awesome season. You can’t take anything away from him. He’s such a good competitor. I knew tonight was going to be a long shot. Nine points [to make up], especially going up against a guy like him, it’s nearly impossible. I did the best I could, rode really well at the end of the season; obviously missed that one race win that I needed. But you know what, we rode really well, and can’t thank my team enough [and] the fans. And we’ll be back for outdoors and SMX. We’ve got two more championships to go after, so [we’ll] just try and build for next year, try and start off like this, and we’ll be in a good spot.” – Chase Sexton, when asked about his impressive speed in the final rounds of the season.
“[This third championship] means everything. You don’t know how many nights I’ve woken up just wanting to get this again. And I never thought I’d be here again, so never give up on yourself. Never cut yourself short. I’m not maybe the best, but man, when you put your mind to something [then] you get it done. I’ve got to give it up to the Good Lord, my wife, my family. Man, they push me to be the best every day. And Yamaha for giving me another opportunity; I knew I wasn’t done after those two [championships]. It feels freakin’ awesome, man. I just couldn’t do it without everyone involved, the whole Star team… I wasn’t supposed to line up this January [due to injury] and I did and here we are. It means the world. This may never happen again so I’m going to enjoy the [heck] out of it. Thank you to all these fans, great team, teammates, everyone. It’s just a relief. Never give up on yourself, kids!” – Cooper Webb (with members of the Monster Energy Yamaha Star Racing team)
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.
“That was wild. I just heard bikes revving behind me, [I was] like, ‘Oh my God, they’re going at it!” I’d seen Seth for a second and then he was gone, and I was like, ‘Oh, no, they got into it.’ But congrats to Tom on the Championship, that’s super cool. And dude, the crowd was going wild. That was dope. Thank you to everyone, thank you to my fans for supporting me and my whole Monster Energy Star Racing Yamaha team, love you guys.” – Haiden Deegan
“I had a great start. My first five or six laps were actually really good. I was feeling good, and I was like, ‘Okay, this is mine.’ And [then] I started to make a few mistakes and Seth and RJ got me. They got a little gap, and my only chance was that… if something happened [to Hammaker and Hampshire], and that’s what happened tonight. I feel like that was all year, the whole Championship has been up and down, and I could capitalize tonight, and I’m really pumped.” – Tom Vialle (with members of the Red Bull KTM Factory Racing team)
