The American inks a two-year deal and will make his Triumph´s debut at the 2026 Supercross of Paris this 21 and 22 of November.
5.11 Triumph Factory Racing is pleased to officially welcome Aaron Plessinger to its SuperMotocross World Championship programme. The experienced American has signed a two-year agreement to race the TF 450-X in the AMA Supercross and Pro Motocross championships.
One of the most recognisable personalities in American motocross, Plessinger brings a wealth of experience and proven race-winning pedigree to 5.11 Triumph Factory Racing. The incredibly popular racer will play an important role in the continued development of the team and the TF 450-X as Triumph targets further success at the highest level of racing in the United States.
Plessinger’s arrival marks the beginning of an exciting new chapter for both rider and team. Having closely followed Triumph’s rapid progress since entering top-level motocross competition, the American shares the team’s ambition to fight for race victories and championships as the programme continues to develop.
Before preparations for the 2027 season begin in earnest, Plessinger will make his first official appearance for the British manufacturer at Triumph’s Global Dealer Conference in Thailand from October 6-9. There, he will be welcomed into the Triumph family in front of approximately 1,200 dealers from around the world.
Following the event, Plessinger will return to the team’s facility near Atlanta, Georgia, to begin working with the TF 450-X and establish his base settings. His first competitive outing aboard the Triumph will then come at the Paris Supercross in November, before an extensive testing and development programme gets underway ahead of the 2027 SuperMotocross World Championship.
As a highly experienced racer in both AMA Supercross and Pro Motocross, Plessinger will bring valuable knowledge to the team as it looks to take another step forward in its 450 programme. Alongside his racing credentials, his enthusiasm and likeable personality make him a natural fit for the Triumph brand and team.
“I’m super excited to be joining 5.11 Triumph Factory Racing. I’ve been watching what the team has been building over the last few years and I really believe in the potential of both the team and the TF 450-X. We all want the same thing, which is to win races and fight for championships, and I’m excited to be part of that journey. I’m looking forward to getting to know everyone, spending time with the team in Thailand at the Global Dealer Conference, and then getting back to Georgia to start testing properly. The Paris Supercross will be a great way to begin this new chapter, and after that we’ll really get to work preparing for the 2027 SuperMotocross season. Hopefully I can bring plenty of good times, some victories, and put Triumph right in the fight for championships.”
