Red Bull KTM Factory Racing’s Aaron Plessinger has captured an emphatic first 450SX Main Event victory of season 2025 at Round 12 of the AMA Supercross Championship in Foxborough, overcoming treacherous conditions to clinch a well-earned, popular win inside Gillette Stadium.

Plessinger made the most of his mud riding skills by sealing the third-fastest time in the afternoon's sole 450SX qualifying session.

Continuing his momentum into the Heat Race, ‘The Cowboy’ would claim a convincing second-place finish following a measured performance, setting him up well for the upcoming Main Event as the conditions intensified.

Getting off to a fast start in the shortened Main Event, Plessinger patiently powered his way to the front of the field during the race's early stages, before stretching out to a 25-second lead across the nine-lap encounter, claiming what was a heroic first race win of the season.

On Winning the Main Event

“I was nervous in the lead up! In a mud race, you never really know what’s going to happen – you can be as confident as you can be, but when that gate drops, you never really know. We pushed to the front as soon as we got out of the first turn clean in the Main, managed to keep it on two wheels and tried to cruise it on in, but it wasn’t an easy cruise by any means. It was tough, but I had a lot of fun! I'm stoked for the team, who never stopped believing in me even when things were tough at the beginning of the season. I can't thank them enough for that.”

This one a lot different than your San Diego win?

Yeah, San Diego was a little muddy, this was a whole different breed, man. Like Shane said, when the rain stopped and the mud tacked up, it got so heavy, and it was almost like when your foot touched the ground, it almost wanted to stick there. It’s hard to explain unless you were out there. In the heat race, my dad was texting my wife, telling me to stand up, and I wish he was here because that was a lot harder of a task than any other old mud race! It was kind of like slot car racing – you just take the rut and stay in it for the rest of the section. But no, it felt really good, honestly. Today doesn’t feel like a real Supercross because we only had one qualifying, and we were sitting around until about 1:30, so yeah, it just feels like a weird day. That main event took it out of me, I’m pretty tired now, and yeah, I’m going to rest up tonight and rest happy.

Only rider racing and going for it.

Yeah, I knew when I didn’t get the holeshot, I had to pin it to the front or else my goggles were going to be destroyed. I picked tear-offs for the main event, so I didn’t get any water under my rolloffs, so I knew I had to get to the front quickly. In that condition, when the track’s still fresh, I mean as fresh as, you know, they bladed it with the dozer, it was still deep, but you can kind of push it and not really worry about the ruts because some of them are gone. You’ve got to look ahead because they like to back-blade a little bit behind the start of the rut, so you’ll be going through a flat section, and then you come into the rut. So it’s a little bit sketchy, you just got to look forward. But that first lap, I knew I had to get to the front, and I kind of was worried about my clutch during the end of the race because that first lap, I was really giving her the beans.

Decision on set-up.

I just went a little bit softer on everything. It wasn’t like huge changes, but I just told the guys I needed a little bit more feel, and I was struggling a little bit to stand up in the heat race. So yeah, I just told them to soften everything up, and I’ll let her eat because, really, in this stuff, the team can’t help you that much. It’s just a kind of survival and get a start and try to get out front, and the rest is pretty much up to you.
