Welcome to the next level moto.
Red Bull KTM Factory Racing's Tom Vialle has finished runner-up in the 250SMX Class of the 2024 SuperMotocross World Championship (SMX) following the final round at The Strip at Las Vegas Motor Speedway. Vialle qualified fifth on the KTM 250 SX-F FACTORY EDITION and put himself in good position during Moto 1, taking the checkered flag in third position. The two-time MX2 World Champion and this year's AMA Supercross 250SX East Champion was challenging for the lead in the final encounter when he went down, managing to remount for a P8 result. Those finishes positioned the Frenchman fifth overall for the round, which in turn saw him captured second in the 250SMX World Championship for season 2024. Tom Vialle: "I'm pretty happy, the result was good this year, and we were strong across each series. I had a bad start in the first moto and then the second one was better, but I was really frustrated after the second moto because I was feeling really good before the crash. It was a little bit up and down this season, so now I look forward to the Nations and that will be a lot of fun next." Las Vegas started strongly for rookie teammate Julien Beaumer in qualifying second on the combined timesheets, but he was affected by poor track position across the two motos. After completing Lap 1 on 17th, he climbed to 11th in Moto 1, and then finished Moto 2 in ninth for P9 overall. He was seventh in the final 250SMX standings. Julien Beaumer: "Tough night! My riding was really good, I just didn't execute the starts, and on a track like this you need that track position early because it's hard to pass. It's been a good year, we made some big steps as a rookie, and the plan is to be up front next year." Red Bull KTM Factory Racing rider Aaron Plessinger was a picture of consistency tonight in the 450SMX class. After qualifying his KTM 450 SX-F FACTORY EDITION in P9, The Cowboy went 4-4 for fourth overall in Las Vegas, which also placed him P4 in the SuperMotocross World Championship for 2024. Aaron Plessinger: "Vegas was a really good. I was comfortable on the bike from the start and I had a really good start in the first one, ended up getting fourth in that, so I was pumped. Second moto, I rode really good again, and went fourth again, so after the last two weeks I will take that, for sure. We also moved to fourth in the points, so it was a good way to end the season like that." After entering the SMX Final in contention for the 450SMX title, reigning AMA Pro Motocross 450MX Champion Chase Sexton's chances unfortunately ended prematurely on the opening lap of Moto 1 tonight. The Red Bull KTM rider came together with another rider and injured his right hand, which ruled him out for the remainder of the evening. After finishing third in the AMA Supercross 450SX Championship and dominating the outdoors, Chase was placed seventh in the final SMX standings. An update on the extent of his injury will be made available after he undergoes further medical evaluations. Results 450SMX Class – SMX Final 1. Jett Lawrence (AUS), Honda 2.

Red Bull KTM Factory Racing's Chase Sexton won the second 450SMX moto and claimed P2 overall in Playoff 2 of the 2024 SuperMotocross World Championship (SMX) post-season at Texas Motor Speedway, as teammate Tom Vialle finished second in the 250SMX Class. Both are in title contention entering next weekend's SMX Final. After setting the pace in Free Practice on Friday, Sexton qualified his KTM 450 SX-F FACTORY EDITION fourth in Fort Worth. Moto 1 saw the reigning Pro Motocross Champion sprint to P4, but he was saving his best until last when he took a commanding second moto victory with a winning margin of 9.897s. That placed him second on the podium, and with triple points on offer in Las Vegas, Sexton sits one point outside of the series lead in what will be a winner-takes-all scenario next Saturday night. Chase Sexton: "Getting a start is one of the key factors, but we actually made a change right before Moto 1 and I felt like I rode pretty well, but was just way back. In Moto 2, I got a good start and was able to ride my own laps – I felt like I did back in Pro Motocross. It was a good race, we ended up second overall, so we will try to keep building and come out swinging for Vegas!" Still managing the effects of his crash from Charlotte one week ago, 450SMX teammate Aaron Plessinger was eighth in combined qualifying, and then went on to record 9-7 scores for seventh overall in a gritty performance from 'The Cowboy'. Plessinger is currently ranked fifth in the premier class title race with one round to go, motivated to finish on a strong note at the SMX Final. Aaron Plessinger: "Second playoff of SMX went okay – I rode my outdoor suspension on this one and it was a little soft. I got off to a pretty bad start in the first one, was working my way up, and jumped off the track, so finished ninth. In the second one, I got a really good start, was running up front and my shoulder started feeling it, and I ended up dropping back to seventh. Not where we want to be, but we will try to improve a little bit for Vegas and the final round." Texas saw current 250SX East Champion Tom Vialle rebound for his first 250SMX podium of the year in second overall onboard the KTM 250 SX-F FACTORY EDITION. After qualifying in position six – within a second of the fastest lap time – Vialle finished third in Moto 1, then charged to a confidence-inspiring second as the checkered flag flew in the final encounter. He is now P2 in the standings, 19 points outside of the lead entering Las Vegas. Tom Vialle: "We are happy with the result today. The track was not easy – the same for everyone, of course – but I kept pushing until the very end. In the final moto, I was catching Haiden [Deegan] a little bit, but came up short. It was nice to be in the fight and it was a good race to get us ready for next weekend." Last weekend saw rookie Julien Beaumer earn a first-career podium and he backed that up with P5 this weekend at SMX Playoff 2. While not entirely satisfied with his result, it was another promising performance from the teenager, as consistent 5-6 results placed him inside the top five overall. Beaumer is also positioned fifth in the championship tally, eager to finish strongly at next weekend's decider. Julien Beaumer: "It was a tough day for me. I never really had the feeling I was looking for on this track, but P5 was a good result. We got a little bit better in that second moto, so not my best day, but fifth on a weekend that I didn't feel too good, we will take that and be ready to fight going into Vegas."
