The 2025 SMX World Championship rumbles into the playoffs this weekend, and SuperMotocross fans have already started to plan out their watch parties.
Saturday's event at zMAX Dragway at Charlotte Motor Speedway will feature the top Motocross riders from the Monster Energy AMA Supercross Championship and the Pro Motocross Championship.
The riders will compete on a custom-built course at zMax Dragway. The opening round of the playoffs will feature a two-moto format for the 450cc class and the 250cc class, which should provide for plenty of drama and excitement as soon as the gates drop.
In the 250 class, it's been all Haiden Deegan. The young phenom has gone a perfect four-for-four in motos to start the season and is now chasing a flawless campaign, a rare and elite feat in motocross history.
