After a two-year stint overseas racing the FIM Motocross World Championship (MXGP) and other championships and races, Jack Chambers is back in the U.S. The Florida native has announced a new deal for the 2025 SuperMotocross World Championship (SMX) season as he will race with the Partzilla PRMX team.

Chambers posted the news to his Instagram page, saying: “I’m back on home soil after two seasons of racing MXGP in Europe, looking forward to the challenges that come with racing supercross again!”

Chambers raced two rounds of the AMA Pro Motocross Championship in 2021 before making his Monster Energy AMA Supercross debut in 2022. After two rounds of supercross in 2023, Chambers had the opportunity to go overseas and race with the Big Van World MTX Kawasaki team.

In 2023 and 2024, Chambers finished 17th and 19, respectively, in the MX2 championship, finishing with a best of 12th overall two separate times in 2024.
