Red Bull KTM Factory Racing's Tom Vialle charged to a hard-fought podium finish in Round 4 of the 2025 AMA Pro Motocross Championship at the High Point National, as 450MX teammate Aaron Plessinger impressed once again with an opening moto podium and fourth-place result overall. Two-time MX2 World Champion and current 250SX East title-holder Vialle posted a strong performance at the fourth round of the season in Pennsylvania, powering his KTM 250 SX-F FACTORY EDITION to fourth position in the opening moto of the weekend. An elevated P2 performance in Moto 2 was enough for the Frenchman to claim second overall – marking his second podium in the opening for rounds – and he maintains fifth in the 250MX standings in these early stages of the series. Tom Vialle: "My last two results haven't been where I wanted them to be, so coming in here the plan was for sure to be on the box, and we accomplished that. Looking forward after the weekend off, I feel comfortable at Southwick, and we've done a lot of work these last couple of weeks, so I am looking at turning things around and hopefully getting another good result." 250MX teammate Julien Beaumer began his weekend with P8 in qualifying, before two difficult motos with 15-40 scores onboard his KTM 250 SX-F FACTORY EDITION leaves the number 23 with his sights set on Southwick after the break. He is currently ninth in points following Mt. Morris. Julien Beaumer: “It was a tough day in High Point for me. Moto 1 was going good, and then I crashed with three laps to go. Moto 2, better start, and I made some good passes on lap one, but then I had a good crash at the mechanic's area. We'll rest up now and get ready for Southwick." Plessinger's High Point National began with him setting the sixth-fastest time in 450MX qualifying, before taking his KTM 450 SX-F FACTORY EDITION to the lead during the early stages of Moto 1. 'The Cowboy' would go on to finish third in another positive outing. A strong start in Moto 2 saw Plessinger again in the mix with the front-runners, however, the skies would open up and cause chaos for the field, with the number 7 entering the pits for fresh goggles. With the race red-flagged soon after, a P4 finish also earned him fourth overall, and he sits third in the 450MX championship. Aaron Plessinger: “High Point was a good day. First moto, I got a good start, then Jett [Lawrence] stalled it and I led for a little bit, but I got a bit tight for a while there and I finished P3 in that one. Second moto, I didn't know it was going to rain and I picked the wrong goggles. [My] tear-offs were gone, had to pull in, and then pretty much straight after that, we got red-flagged. Overall, still P4, so I can't be too mad! We'll have a weekend off and get ready for Southwick." Next Race: June 28 – Southwick, Massachusetts Results 450MX Class – High Point National 1.
