The FIM World Supercross Championship today announces three rider line-up changes ahead of the 2025 season opener at the Buenos Aires City GP on 8 November.

French rider Tom Vialle has withdrawn from his planned wildcard appearance at the Australian GP in Gold Coast (29 November) due to unforeseen scheduling conflicts.

In the SX2 class, Frenchman Anthony Bourdon will join defending champion Shane McElrath on the Quad Lock Honda team, stepping in for Kiwi Brodie Connolly, who has been sidelined with injury.

Meanwhile, nine-time Australian champion Matt Moss will replace Frenchman Quentin Prugnieres aboard the Venum Bud Racing Kawasaki 450 machine.

The 2025 FIM World Supercross Championship kicks off next week in Buenos Aires, Argentina, before moving on to Vancouver (15 November), Gold Coast (29 November), Stockholm (6 December) and Cape Town (13 December).
