Updated chain glider design for improved mud dissipation.
Upgraded suspension settings at both ends in support of the updated frame and rear linkage, improving weight distribution, stiffness, and response.
Upgraded rear brake pedal construction for increased stiffness and resistance to bending.
New fuel tank roll for improved fitment, reducing frame scrubbing, and enhancing durability.

2025 KTM 150 SX BACK ON THE ATTACK
After a 2-year absence, the 2025 KTM 150 SX is bringing the 150 cc designation to a table-top near you. With a lightweight chassis, and a pure READY TO RACE attitude, the KTM 150 SX is back to set a whole new benchmark.
The 2025 4-stroke KTM SX-F stable is bred to dominate.

The MX scene has just become a one-horse race.

Welcome to the next level moto.
Red Bull KTM Factory Racing’s superb 2025 MXGP continued with more outstanding results at the historic Loket circuit for the Grand Prix of Czech Republic this past weekend. Lucas Coenen rode his 450 SX-F to 1st place for the second meeting in a row and for his tenth podium at round 14 of 20: the first meeting of a fresh double header. In the MX2 class championship leader Simon Laengenfelder got back in the groove with victory ahead of Andrea Adamo; both on the conquering KTM 250 SX-F.
Reigning 450MX Champion Chase Sexton returned to the winner's circle in Round 8 of the 2025 Pro Motocross Championship at the Washougal National on Saturday, claiming a 1-2 moto scorecard for a convincing first overall victory of the season. Red Bull KTM Factory Racing's Sexton powered his KTM 450 SX-F FACTORY EDITION to the second-fastest time during 450MX qualifying, quickly gaining comfort on the hard-pack, slick surface of the Washougal circuit. In Moto 1, Sexton launched to a top-three start, only to make a decisive pass in turn two to enter the race lead. From there, a spectacular performance saw the 25-year-old pick up his first race victory of the outdoors since returning to competition at the RedBud National. For the second moto, Sexton featured up front once more, running inside the top three before a red flag briefly halted proceedings. Once the race recommenced, the number 1 ran in second position for the duration, with his combined scorecard earning him the Washougal National overall win. The Pro Motocross Championship will now take a two-week break before returning for the final three rounds, beginning at Ironman Raceway on August 9. Chase Sexton: "It was nice to get a win today! It’s been a while since I have won a race – since the Salt Lake City Supercross – so it’s good to get that monkey off my back and go into the break with momentum. I still have a few things that I can improve on, but my speed was better today and I’m stoked to click off a win. Not eating roost in that first moto was nice… Second moto, I ate a lot of roost and I didn’t like it at all. But it was important to get creative and make quick passes here, as the roost feels like you’re getting hit with a paintball gun for 30 minutes. Thanks to the team for today, it's a good feeling to stand back on top of the podium." Next Race: August 9 – Crawfordsville, Indiana Results 450MX Class – Washougal National 1.

Red Bull KTM Factory Racing rider Tom Vialle has been sidelined ahead of Saturday's Pro Motocross Championship round at Washougal, unable to ride this week following a hard impact at the Spring Creek National that left him with soreness in his knee and shoulder. Equipped with the KTM 250 SX-F FACTORY EDITION, Vialle raced to a sixth-place finish in the first 250MX moto at Millville, before an unfortunate fall entering the sand whoops on the opening lap of Moto 2 saw the current 250SX East title-holder retire from the race. As a result, Vialle together with the full support of his Red Bull KTM Factory Racing Team, has made the decision to withdraw from this weekend's race in Washington, before taking advantage of the two-week break that is scheduled prior to Round 9 at Ironman Raceway on August 9th. Ian Harrison, Red Bull KTM Factory Racing Team Manager: "It’s definitely unfortunate to announce that Tom Vialle will be sitting out this weekend’s race. It’s a long and demanding season for our riders, and we’ve been extremely fortunate up to this point to have had a full roster through the majority of Supercross and Pro Motocross. Of course, we love seeing our entire team out on the track representing the Red Bull KTM Factory Racing program, but our riders’ health and safety always come first. We fully support Tom’s decision to take the weekend off so he can focus on finishing the season strong and continuing to fight for podiums." Vialle is currently positioned fifth in this year’s 250MX standings following 7 of 11 rounds, with a pair of P2 overall results at both High Point and Southwick marking his best results of the outdoor season to date. He is also currently positioned third in the SuperMotocross World Championship (SMX) points.
