In the sweltering heat of Rice-Eccles Stadium, the 2025 Monster Energy AMA Supercross Championship concluded with a dramatic finale that saw Cooper Webb secure his third career championship while Chase Sexton delivered an emphatic statement victory in Salt Lake City.

Red Bull KTM Factory Racing’s Chase Sexton grabbed his seventh win of the season with a commanding performance, choosing to pull clear of the field rather than employ tactics to influence the points battle. The victory showcased Sexton’s exceptional speed that has been on display throughout the latter part of the season, though it ultimately proved too little, too late in the championship chase.

“A little bit too late, obviously. Cooper had an awesome season. You can’t take anything away from him,” Sexton acknowledged after the race. “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.”

Meanwhile, Monster Energy Yamaha Star Racing’s Cooper Webb secured his place in the sport’s history books by taking a calculated fourth-place finish, earning enough points to claim the 2025 championship. The title places Webb in elite company as just the seventh rider in the sport’s history to earn three or more premier class Supercross championships.

“[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,” an emotional Webb said after clinching the title. “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.”

The Salt Lake City crowd was treated to an impressive charge from Rockstar Energy Husqvarna Factory Racing’s Malcolm Stewart, who started in seventh but methodically worked his way through the field. Stewart reached the top three positions by the race’s midpoint before ultimately securing second place.

“I knew I had to give it everything I had. I wanted to get back up on the box,” Stewart said. “Last weekend stung a little bit, so I’m like, ‘You know what, I’m giving it everything I’ve got. This is the last race, round 17, so we’re going to give it everything we’ve got.'”

Monster Energy Yamaha Star Racing’s Justin Cooper rounded out the podium, securing his third consecutive top-three finish to close out the Supercross season. His performance also locked up third place in the championship standings.

“It’s been a great end to the season. Three podiums in a row, so it’s definitely special for me. I don’t take those for granted,” Cooper said. “Third in the championship is really special for me, and we’ll take it into outdoors now.”

The Dave Coombs Sr. 250SX East/West Showdown provided perhaps even more drama than the premier class as three riders entered the finale separated by just three points in the battle for the Eastern Regional 250SX Class Championship.

Monster Energy Yamaha Star Racing’s Haiden Deegan, who had already wrapped up the Western Regional 250SX Class title the previous weekend, grabbed the holeshot and was never challenged en route to his fourth win of the season.

Behind Deegan, however, a fierce battle unfolded that would determine the Eastern Regional champion. Red Bull KTM Factory Racing’s Tom Vialle, Monster Energy Pro Circuit Kawasaki’s Seth Hammaker, and Rockstar Energy Husqvarna Factory Racing’s RJ Hampshire engaged in an epic duel that featured aggressive passes and dramatic position changes.

The championship fight took a decisive turn when contact between Hampshire and Hammaker sent both riders to the ground. This allowed Vialle to slip past and secure a position that would ultimately give him his second consecutive Eastern Regional 250SX Class title.

“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,'” Vialle explained. “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.”

Red Bull KTM Factory Racing’s Julien Beaumer finished second in the race, with Vialle taking third and the championship. Hammaker recovered to finish fourth but fell short in his title bid.

“It was a great season. Came up a little short, that one’s a bummer when you get that close,” Hammaker said. “That was a crazy race. Got off to a decent start and just chaos from there.”

With the Supercross season now complete, riders will shift their focus to the 11-round AMA Pro Motocross Championship this summer. Following the outdoor season, the top performers from both series will advance to the SMX World Championship in September.

The three-round SMX playoffs will feature increasing points values at each event, with the finale in Las Vegas on September 20th offering triple points. Peacock will stream every moto of both the motocross season and SMX World Championship live, with select events also available on NBC and USA Network.

As Webb celebrates his third Supercross title and Vialle his second consecutive 250SX East championship, the attention now turns to whether they can carry their momentum into the outdoor season and potentially claim the coveted SMX World Championship that will crown the most versatile riders across all disciplines of professional motocross racing.
