Ironman RacewayTeam USA has called upon RJ Hampshire as a late addition to its lineup for the 2025 FIM Motocross of Nations (MXoN), to be staged at Ironman Raceway from October 3-5.
Rockstar Energy Husqvarna Factory Racing's Hampshire has been exceptional since stepping up to the Husqvarna FC 450 Factory Edition ahead of the Pro Motocross Championship this season, in which he finished fifth in the final 450MX standings.

Hampshire continued that form in the SuperMotocross World Championship (SMX) Playoffs and Final, climbing to seventh position following another convincing showing during the post-season.

Just over one week out from the Nations returning to American soil, Hampshire has been drafted into Team USA as a replacement rider and is incredibly excited for the opportunity to compete in the Open category at home.

It will be the 29-year-old's second time representing his country in the historic international event, adding to his appearance in 2023 at Ernée, France.
"I am really excited for the chance to represent our great country on home soil!" Hampshire commented. "I may not have been the first pick, but I’ll always answer the call, and you know I’ll give it everything I’ve got. Ironman is one of my favorite tracks and we’ve still got a strong team ready to go – see you all next weekend!"
Rockstar Energy Husqvarna Factory Racing is proud to provide its full support to Hampshire and Team USA in a bid to reclaim the Chamberlain Trophy in Indiana. The United States last won the MXoN in 2022 when it was staged at RedBud.
"It’s such an honor when one of the Rockstar Energy Husqvarna Factory Racing athletes are selected for MXoN," explained Nathan Ramsey, Rockstar Energy Husqvarna Factory Racing Team Manager. "RJ is a perfect choice to represent the USA, as well as our team. He will no doubt give it everything he has to get the job done and we are more than happy to support him and Team USA!"
