Haiden Deegan's domination in the 250 class came full circle this season, earning him the 2026 250W Supercross Championship– With all of the preparation that's led up to moments like these, it's so rewarding to see everything come together for Haiden to get it done. As we finish the last couple rounds of Supercross, we'll be starting to prep for his 450 Motocross debut in the meantime... so stay tuned for these wild times!

There was one more box for Deegan to check off before moving on to the 450 class – defending his 250SX West title in dominant fashion. Well, it was mission accomplished for the 20-year-old Californian in St. Louis.

“That was sick,” said Deegan. “Seven in a row, too. That was a fat lead. It’s just heart, baby. We’ve been digging, but we're just getting started,” said Deegan. “I'm going to go to Nashville and have some fun. We’re still going to stay in line because we have a whole other goal to chase – 450 outdoors. But for now, we'll celebrate this 250 title. Man, it feels good!”

It was another masterclass performance from Deegan at The Dome at America’s Center. He opened the night by winning the nine-lap 250SX West Heat Race by an impressive 13-second margin.

In the East-West Showdown Main Event, he quickly worked his way into second in the opening laps, passed teammate Cole Davies on Lap 7, and rode on to claim another commanding victory, and by doing so, secured the championship a rare three rounds early.

“I'm stoked to win it and especially win it three rounds early, do some history book stuff right there, even though they're trying to take it away from me [the win streak due to a penalty a few weeks ago] but we got it done.

"I'm really grateful that it kind of took me a little longer to win a supercross title because it let me learn. It kept me in the class long enough to keep learning, and I feel like this year I finally ticked off a lot of the boxes that I needed, where I feel like if I would have went 450 last year I didn't have everything I needed.

"So, I really think this was a good thing. We won a title last year but we were able to race this year as well, keep building. I feel like one thing that was hindering me was just the whoops. Really just a lot of early mornings trying to get those dialed. It switched the path for me. I feel like if you can hit whoops you can win races, so. I mean it takes a little more than that obviously too, but that does help it a lot. I feel like it's just a lot more consistent in them and it's really helped overall.”
