SuperMotocross (SMX) is a world championship that combines Supercross and Pro Motocross, two types of off-road motorcycle racing. SMX was created in 2023 after the producers of Monster Energy AMA Supercross and the AMA Pro Motocross Championship announced they would work together to create a new set of postseason playoff races. The SMX season consists of 31 rounds that conclude at the LA Memorial Coliseum in October.

The SMX races are held in stadiums and have elements of both Supercross and Motocross. The tracks are typically shorter in length than a standard Motocross track. The top 20 riders from combined Supercross and Pro Motocross standings are automatically seeded into the SMX playoffs, while riders in positions 21-30 overall, in addition to any rider who has won a main event/overall in either series, will also be eligible but will have to qualify for the 22-rider field within the remaining two gate picks.

The SMX races are streamed on Peacock within the US and coverage also extends across NBC and its NBC Sports networks. International viewers have a SMX Video Pass made available to watch Supercross, Pro Motocross, and the SMX series live from all 31 events throughout the season.

In summary, SMX is a world championship that combines Supercross and Pro Motocross, held in stadiums with elements of both types of racing. The top 20 riders from combined Supercross and Pro Motocross standings are automatically seeded into the SMX playoffs, and the races are streamed on Peacock within the US and available to international viewers through the SMX Video Pass.
