Team GB’s 2026 Motocross of Nations result in Ernée, France, has officially been wiped from the books. The FIM confirmed Nov. 5 that Race Direction disqualified MX2 rider Ben Mustoe (No. 47) from the entire event after the fuel sample from his bike “did not correspond to any FIM certified race fuel category 2.” Under FIM rules, a rider’s disqualification takes down his national team, so Great Britain loses all of its results, trophies and prizes.
Mustoe’s GasGas was one of nine bikes picked at random for fuel checks on race day, Oct. 4, a group that also included the bikes of Cooper Webb, Lucas Coenen and Roan van de Moosdijk. Race-day results had Ben Watson, Taylor Hammal and Mustoe seventh on 82 points, but the FIM’s updated classification now lists Great Britain at the bottom, disqualified “due to usage of non-conform fuel by one of their riders.” Switzerland moves up to seventh, and nothing changes at the front, where Belgium’s Lucas Coenen, Sacha Coenen and Liam Everts keep the Chamberlain Trophy on 23 points ahead of Spain on 26 and the Netherlands on 34.
The FIM says no appeal was lodged with the FIM Stewards Panel before the deadline, so the decision is final. The ACU said in a statement that it and Team GB “acknowledge and accept the decision of Race Direction,” adding that “there is no suggestion the irregularity provided a competitive advantage or resulted from any deliberate attempt to circumvent the regulations.” Both are reviewing how it happened.
Team manager Mark Chamberlain took the blame, calling it “a genuine mistake” in an interview with GateDrop and saying an additive in the fuel was over the legal limit. He was quick to clear his rider. “It’s not on him,” Chamberlain said, adding that “it’s not for a rider to check.” He said the team will have “a more robust system” going forward.
