“I’m super excited to be joining 5.11 Triumph Factory Racing,” Plessinger said. “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.”

I know what Aaron is capable of, I know the determination and personality he brings to a race team, and I truly believe we have the right people and programme around him to be successful.
