Haiden Deegan Going 450 for WSX Races in Argentina and Australia
October 24, 2025, 10:05pm
A big change today, as the FIM World Supercross Championship has announced Haiden Deegan will race a 450 in his two wild card races in the series, in Argentina and Australia. Deegan was originally announced as a SX2 (250) rider in Argentina, but we spotted a social media post from Deegan this week with a 450, and now it's been announced that he's going big (bike) at these races. The supercross debut on the 450 takes place on November 8th.
As you can see from above, Deegan will race a 450 when it's time, and it's time now.
Deegan is expected to race the 250 class of Monster Energy AMA Supercross in 2026 before jumping to the 450 class full-time in Pro Motocross. Or will there be more big-bike announcements coming?
