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. Equipped with the KTM 450 SX-F FACTORY EDITION, 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. Aaron Plessinger: “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.” Following what was his fourth podium result in the past five races, Plessinger currently sits seventh and continues to make ground in the 2025 championship standings. 450SX teammate Chase Sexton piloted his KTM 450 SX-F FACTORY EDITION to the second-fastest qualifying time inside Gillette Stadium, seizing his window to post a lap time in track conditions that were worsening by the lap. The rain continued to fall as he lined up for his Heat Race, with the number 4 proceeding to put on a clinic of patience and balance, crossing the finish line stripe in first place by over 30 seconds. He was later penalized by two positions for jumping on a red cross section of the track. In the Main Event, Sexton endured a mid-field start before climbing his way toward podium contention throughout the middle stages of the race. An untimely fall, however, in a difficult position on the circuit saw Sexton surrender a podium finish and was instead able to salvage a sixth-place result in a challenging night of racing. Chase Sexton: "The round started off well for me. P2 in qualifying, then won my Heat Race, but got docked those positions. That led to a bad gate pick in the Main and a terrible start, but overall, not a great Main Event. I fought as hard as I could and we’ll get ready for next weekend to rebound stronger.” The 250SX East Class returned to action in Foxborough, with defending champion Tom Vialle recommencing his pursuit for a second-consecutive crown. Onboard the KTM 250 SX-F FACTORY EDITION, Vialle took his Heat Race victory to open the night program. Once the gates dropped on the Main Event, Vialle was running strong inside the top-five before a series of incidents in the closing stages of the race significantly hampered his final result, eventually credited 22nd position. Despite his troubles, the Frenchman maintains the Eastern Division red plate. Tom Vialle: "We finished up in Foxborough and it was a really rainy day here. I managed to win my Heat Race, and then the track was really challenging for the Main Event. I had a bad start and came back to fifth, and then had a crash with two laps to go, which kept us from finishing the race. I’m now tied with Seth [Hammaker] in the championship and it’ll be a good fight with four rounds to go until the end.” Next Race: April 12 – Philadelphia, Pennsylvania Results 450SX Class – Foxborough 1.

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.
