Red Bull KTM Factory Racing’s Chase Sexton and Aaron Plessinger raced to a pair of podium finishes at Round 11 of the 2025 AMA Supercross Championship in Seattle tonight, with Sexton claiming a hard-fought second position and Plessinger taking third place in a lively 450SX Main Event. Sexton powered his KTM 450 SX-F FACTORY EDITION to the second-fastest qualifying time inside Lumen Field, posting a lap time of 47.121s on a circuit recognized for its technical, rutty conditions. That momentum would continue into his Heat Race, overcoming an average start to steadily slice his way through the field. A spirited ride for the number 4 saw him reach the rear wheel of his Red Bull KTM Factory Racing teammate Plessinger by the race's end, with the team scoring a 1-2 finish. In the Main Event, Sexton entered the lead of the race after clawing his way from a sixth-place start as the difficulty of the Lumen Field conditions intensified. Following a spectacular performance at the front of the field, Sexton ultimately finished in P2 following a final lap showdown for victory. Chase is positioned second in the standings, just 11 points outside of the lead following Round 11. Chase Sexton: "Tonight was gnarly and I think the pace this year was even higher than last year, which is crazy. We were pushing the limit – I was getting that long rhythm, which helped me, and then Coop [Cooper Webb] was faster in the tight stuff. There was a lot of cat and mouse out there, but it was a balance of pushing the pace, while also keeping your balance, because you had to hit your marks and try not to make mistakes, which was almost impossible on that track.” ‘The Cowboy’ claimed the holeshot in 450SX Heat 1, which continued his run of form throughout the recent rounds. Managing the pace at the front, the always-popular Plessinger charged to first position onboard his KTM 450 SX-F FACTORY EDITION, setting himself up well for the upcoming Main Event. Once the gates dropped on the Main Event, Plessinger posted a measured ride on a soft, rutty surface, steadily climbing his way up into a calculated third place finish by the conclusion of the night when the checkered flag flew. Aaron Plessinger: "I got the best jump out of the gates I got all day for the Main Event, then coming into the first corner, I guess I hit the brakes too quickly and stalled the bike. I was trying to bump start it for about 50 feet and smacked right into Malcolm [Stewart], which I feel so bad about as he might’ve been up on the box with us. It happens. I had to ride hard, and it was not an easy track... The ruts here are like no others, it’s like a sponge, which makes it super-wild. Huge thanks to the Red Bull KTM Factory Racing Team for keeping me comfortable on track – let's keep this going!" The 250SX West Class returned to action in Seattle following a three-week hiatus, with Julien Beaumer recommencing his hunt for this year's championship. Equipped with his KTM 250 SX-F FACTORY EDITION, Beaumer collected the second-fastest qualifying time before finishing P2 in his Heat Race. Upon delivering a solid ride throughout the Main Event, Beaumer battled inside the podium placings for the entirety of the race before eventually landing a fourth-place result in Seattle to remain well in title contention. Julien Beaumer: "Fourth place in Seattle, just a bad line choice in the Main cost me a lot. I should have been blitzing the whoops, then I got stuck behind the lapped riders, too, and didn’t make good choices there. I became frustrated, which ultimately cost me a lot of time. Overall, it was a step in the right direction with my riding, as my shoulder is improving, and we’re on an upward trajectory. I'm ready to get back to work and come out swinging in Philly.” Next Race: April 5 – Foxborough, Massachusetts Results 450SX Class – Seattle 1. Cooper Webb (Yamaha) 2.

Red Bull KTM Factory Racing’s Chase Sexton raced to his third victory of the season at Round 10 of the 2025 AMA Supercross Championship, posting a convincing scorecard of results across the three-race Triple Crown format in Birmingham. 450SX teammate Aaron Plessinger and defending 250SX East Champion Tom Vialle also claimed podium results tonight. Equipped with his KTM 450 SX-F FACTORY EDITION, Sexton registered the fastest time in the afternoon qualifying sessions, applying the perfect balance of throttle control and aggression on the dry, hard-packed Protective Stadium circuit. With his starts dialed throughout the night, Sexton was inside the top three during the opening lap of each Race and converted his track position to victory in the opening two encounters. A measured second-place ride in Race 3 was enough to capture the overall. In terms of the championship standings, Sexton now sits eight points down on the series lead as Supercross heads to Seattle for Round 10 next weekend. Chase Sexton: “It’s really nice to get the monkey off my back tonight – it feels like I haven’t won in forever! Getting good starts and the first two race wins was super-important, but it reminded me quickly when RJ [Hampshire] got caught up at the start in Race 3 that anything can happen, so I locked in on executing that start as well. From there, I rode my own race in the last one, tried not to do anything stupid and learn from previous mistakes, but I always thrive in these last eight races, so I’m stoked to kick things off this way.” Red Bull KTM Factory Racing teammate Plessinger featured prominently during the Alabama event, powering his KTM 450 SX-F FACTORY EDITION to the opening two Triple Crown holeshots. After collecting a commendable 2-3-5 scorecard, ‘The Cowboy’ earned third position on the night, which continues his recent run of mid-season form. Aaron Plessinger: “These last couple of races have given me a lot more confidence, and that’s showing in my starts, which put me in a really good position tonight. Ever since Daytona I feel like we’ve been rolling, it gave me the belief that I can run with the boys at the front, and that’s everything to me. So, that combined with the work we’re doing at the Baker’s Factory, means we’re in a really good spot right now!” 250SX East Class number one Vialle also returned to action in Birmingham following the mid-series break, with the ever-consistent Frenchman powering his KTM 250 SX-F FACTORY EDITION to 2-5-3 results across each race, claiming third overall on the night and extending his championship points lead as a result. Tom Vialle: "I felt great from the first practice on the track, I pretty much didn’t change my bike all day aside from a couple of clickers. I want that win, believe me, but I’m also letting it come to me. We’re in a great spot in the championship, although I train during the week to win, so we’ll get back to work during this weekend off for us to try and click one off.” Next Race: March 29 – Seattle, Washington Results 450SX Class – Birmingham 1.

Red Bull KTM Factory Racing's defending Eastern Division Champion Tom Vialle reclaimed the series red plate via a second-place finish at the first 250SX East/West Showdown race of season 2025 in Indianapolis. In 450SX, Chase Sexton earned valuable AMA Supercross Championship points with P3 in the premier class Main Event tonight. Vialle recorded the fifth-fastest lap-time in combined qualifying onboard his KTM 250 SX-F FACTORY EDITION, meeting the 250SX West contenders on-track for the first time this year. His form remained consistent from there, racing to fourth in his Heat as he prepared for the Showdown Main Event. A measured ride following a top-three start in the saw ever-consistent French standout Vialle take a well-earned P2 result in the Showdown on a highly-deteriorated track, with the result seeing the two-time MX2 World Champion climb into the lead in the 250SX East point-standings following four rounds. Tom Vialle: “Overall, today was a pretty good day. I started slow in Tampa and Detroit, then Daytona was a good turning point last weekend – I got close to the win and then the same this weekend. I spent the Main Event behind Seth [Hammaker], and I was trying to catch him, but he was riding good. The track was very tricky tonight, so I am pretty happy with second and we're right in the championship, which is where we want to be." 450SX Class title-challenger Sexton posted the third quickest time in the afternoon’s qualifying sessions, dialing in his KTM 450 SX-F FACTORY EDITION on the rutted, technical Indianapolis layout. In charging to a fast start in the second 450SX Heat, Sexton battled Red Bull KTM Factory Racing teammate Aaron Plessinger at the head of the field during the opening laps, before taking the lead and taking a commanding victory. A top-three start in the Main Event saw the number 4 push the pace in the early laps, keeping the pressure on before a late-race mishap resulted in a third-place finish. With five podiums in nine races, Sexton sits P2 in the championship as the second half looms. Chase Sexton: “Back on the podium and tonight was good early on, with the Heat Race win. In the Main, the line I was taking in the sand rollers just went away and I lost the front, which is pretty easy to do especially when you get down into that clay dirt. It took me four or five laps to get back into my groove, which I did, but by the time I did there were only two laps to go. It's unfortunate, but it's racing. Now we have a week off to regroup and come out in Birmingham strong. Typically, when I come back from the break in the Supercross season I tend to be better, so hopefully I can do that again and get some good momentum back on my side." Also equipped with the KTM 450 SX-F FACTORY EDITION, Plessinger took ninth in qualifying, before a holeshot in his Heat Race saw ‘The Cowboy’ eventually greet the checkered flag in fourth place. Battling inside the top-five for the duration of the Main Event, Plessinger would fall while attempting a pass for fourth, before remounting and continuing an impressive charge, which earned the number 7 fifth place as the momentum towards his season continues to build. Aaron Plessinger: “That was a really, really good ride – the bike’s feeling awesome and a fifth place on this type of night where I hit the ground, I cannot be mad at that. Especially with how the season has been going… it’s been a wild ride, but we are getting through it and getting better and better. Shoutout to Aldon Baker, we’re doing a lot of laps down at the Baker's Factory, but it’s paying off, plus a big thanks to the whole team and everyone behind me.” 250SX West Class prospect Julien Beaumer returned to action in Indianapolis, nursing a shoulder injury sustained at the previous Western Division round. The Arizona native fought through the pain, powering his KTM 250 SX-F FACTORY EDITION to P7 finishes in both the combined qualifying times and in his Heat Race. Come the Main Event, Beaumer salvaged an eighth-place result, which sees him retain second position in the 250SX West point standings, and he continues to remain in title contention leading into Seattle's next round of the region at the end of this month. Julien Beaumer: “I'm happy with my night in Indy. Obviously I came in a little bit down, I haven't ridden since Arlington, so to get P8 in the Showdown was a good night of salvaging points. We'll get back into therapy this week, get back to 100 percent, and back on the bike before Seattle." Next Race: March 22 – Birmingham, Alabama Results 450SX Class – Indianapolis 1.
