RED BULL KTM FACTORY RACING AND CHASE SEXTON BACK ON TOP IN PHILADELPHIA

Red Bull KTM Factory Racing's Chase Sexton earned a pivotal victory at Round 13 of the 2025 AMA Supercross Championship in Philadelphia, gaining valuable points toward his 450SX title prospects with just four rounds remaining.

Sexton recorded the fastest qualifying time via a scorching final lap onboard his KTM 450 SX-F FACTORY EDITION, before charging to a convincing Heat Race win to open his race day.

A come-from-behind ride after a first-turn tangle in the Main Event saw Sexton progressively climb his way through the 450SX field, with a measured performance seeing him take the lead around the halfway point. From there, he would keep the gap to second place to just above four seconds, claiming what was a stellar result for his fourth win of the season.

Chase Sexton: “All I can do, really, is win from here on out, so today was good! I haven’t won a normal Main Event since Anaheim 1, so that was a big focus for me today, and I am happy to have been able to do that. The track was tough, I came into the first turn with AP [Aaron Plessinger] in the Main Event and maybe cut him off a bit too much, and he went down, and I went way wide, so I had my work cut out for me. Overall though, the ride was really good for me. I felt the flow all day today, so that was nice.”

450SX Class teammate Aaron Plessinger posted the sixth quickest time in the afternoon’s qualifying sessions, dialing his KTM 450 SX-F FACTORY EDITION in on the rutted, technical Lincoln Financial Field layout.

A fast start in his Heat Race saw ‘The Cowboy’ circulating in second place, before a decisive move at the middway mark earned the number 7 the second Heat Race victory for the event. Getting another good jump in the Main Event, Plessinger went down in the first turn, clawing his way back to eighth by the time the checkered flag flew.

Aaron Plessinger: “We had a really good day going here in Philadelphia. I felt so good! Great start in the Heat Race, managed to win that one after passing Coop [Webb], then went into the Main Event with first gate pick. Then someone ran it in really hot to turn one and took me down, which really sucked because I felt like I could’ve made a really good run in the points here for the end of the season. It happens, we’ll go into New Jersey and pick up where we left off in the Heat, and hopefully pick up another win before the season is over.”

Defending 250SX East Class Champion Tom Vialle qualified sixth in the 250SX combined times, before a fall while running in a transfer position sent the Frenchman to the LCQ. From there, he would qualify for the Main Event and power his KTM 250 SX-F FACTORY EDITION to sixth place on the night – now sitting within two points of the red plate.

Tom Vialle: “I had a pretty good afternoon going, a good start in my Heat Race, but then had a pretty big crash on lap two, and pretty lucky to be alright after that crash. Went to the LCQ and qualified through there for the Main, and yeah, I didn’t start great with my gate pick. I think I was around 10th and ended up coming back to sixth. The good point of today is that we’re only two back for the championship with three to go, so we’re still right there.”

250SX West Class contender Julien Beaumer returned to action in style in Philadelphia, charging his KTM 250 SX-F FACTORY EDITION to the fastest overall qualifying time of the afternoon. The Arizona native then went to piece a strong Heat Race together, capturing third place entering the 250 Showdown.

A difficult start to the Main Event following an early restart had Beaumer right at the rear of the field, with the number 23 mounting a charge for the remainder of the race and climbing to 12th.

Julien Beaumer: “I started good by qualifying first, Heat Race was decent, and then I had a good first start to our Main Event, but then it got red-flagged. I spun off the gate on the restart and I was dead-last and struggled to get going from there. Not much more to say, we’ve got work to do, and we’ll come out swinging in Denver.”

Next Race: April 19 – East Rutherford, New Jersey

AARON PLESSINGER AND RED BULL KTM FACTORY RACING TO RACE-ON TOGETHER IN 2026

View Profile
Red Bull KTM Factory Racing has re-signed Aaron Plessinger for the 2026 SuperMotocross World Championship (SMX), inclusive of the AMA Supercross Championship and Pro Motocross Championship. This latest contract extension between the pair signifies what will be a fifth-consecutive season together next year. 'The Cowboy' will race-on with the Red Bull KTM Factory Racing Team managed by Ian Harrison, continuing what has been a successful collaboration. Plessinger will once again be READY TO RACE in the high-profile American series, equipped with the KTM 450 SX-F FACTORY EDITION. With a single round remaining in Supercross 2025, fan favorite Plessinger sits sixth position in the 450SX championship standings and with five podiums to his credit. That tally is underscored by a popular second-career premier class victory at the Foxborough round in April, building momentum throughout the 17-round duration. The 29-year-old Plessinger first joined Red Bull KTM Factory Racing in 2022 and has firmly established himself as one of the sport's most popular and competitive riders both indoors and outdoors. He has finished P3 in 450MX for the past two seasons and has also scored top-five finishes in the 31-round SMX World Championship series both of those years – fifth in 2023 and fourth in 2024. In addition to his success in the United States, Plessinger has represented Team USA at the FIM Motocross of Nations (MXoN) on two occasions (2023-2024) since signing with KTM. The Ohio native's highlight came last year at Matterley Basin in the United Kingdom, where he stood second on the Nations podium as the American team's Open Class entry. Aaron Plessinger: "It means everything to me to be part of Red Bull KTM Factory Racing for 2026. I love everybody and everything about this team, it's been an awesome four years together already, and it's flying by, but we're having such a good time. We've had some really, really good results, so to have the team want to keep me around and keep going together, it's really special to me. I can't wait for what the future brings and my focus right now is to get the best results that I can with the team. To build the fanbase that we have is really special as well, because without them and their support we wouldn't be anything. It's always cool to meet our fans, to interact with the KTM Junior Supercross kids and their families at the races, and that's what dirt bikes are all about. To get people on the bikes that we ride and to become KTM riders themselves, it's why we do what we do each race weekend, to give them that added spark and interest in the sport. I'm super-excited for the remainder of this season and now into next year!" Ian Harrison – Red Bull KTM Factory Racing Team Manager: "Looking back on Aaron’s career here at KTM as we move into his fifth year with the brand next year, it's clear how much of an impact he has had. He is more than just a racer, he is an incredible competitor on the track and a huge personality off it as well. From his long hair and cowboy hat to his unique riding style, Aaron truly stands out. He is, and will continue to be, a massive part of the KTM fanbase into 2026. He brings energy, positivity, and authenticity that resonate not only with our team and the other riders, but also with fans, sponsors, and the entire racing series. He's had another incredible season this year after a rough start, showing grit and determination, achieving five podiums and consistent top-five finishes so far, including a victory in Foxborough. We’re proud of who he is and even prouder to have him on our team. His influence extends far beyond results – his connection with people, both inside and outside the paddock, ensures he will be remembered and appreciated for years to come. He is truly one of a kind, and we are excited that Aaron has signed a contract extension for 2026 to continue racing for the Red Bull KTM Factory Racing family."
