About the AMA Supercross / Motocross Championship

The AMA Supercross and Motocross Championships are American-based series recognised by the AMA (American Motorcycle Association). AMA Supercross (AMA SX) races are held on specially prepared man-made courses in baseball fields or stadiums, while AMA Motocross (AMA MX) races are held on outdoor dirt courses with man-made technical sections. The two classes are 450SX/450MX (4-stroke 450cc machines, or 2-stroke 250cc machines) and 250SX/250MX (4-stroke 250cc machines, or 2-stroke 125cc machines), each contested by production motocross racers featuring special tuning. While the AMA-SX series and AMA-MX championship are held in the U.S., they attract top riders from around the world. Both are highly popular—especially the AMA-SX series, which draws crowds numbering in the tens of thousands. Alongside the World Motocross Championship, they represent the pinnacle of motocross racing.
Starting in 2023, the AMA SuperMotocross World Championship has been held as a playoff series between the top-ranked AMA SX and AMA MX riders. The races are held on courses that combine the characteristics of both championships, featuring both technical and high-speed sections. It has proved a popular competition to determine the strongest rider in American off-road racing.
Kawasaki competes in 450SX/MX with the Kawasaki Motors Corp., U.S.A. (AKM)-operated Monster Energy Kawasaki team, and in 250SX/MX with the AKM-supported Monster Energy Pro Circuit Kawasaki team.
Jason Anderson returns for his fourth year with the Monster Energy Kawasaki. His new teammate is Jorge Prado, a two-time champion (2023, 2024) in the World Motorcross Championship's top MXGP class. The proven lineup will be pushing hard to take home the Supercross and Motocross titles.

In the AMA Supercross and Motocross Championships, the Monster Energy Kawasaki team competes with the KX450. Designed to put expert riders on the top step of the podium, the KX450 base model has always featured the latest in advanced technology. Featuring finger-follower valve actuation, the highly tuned liquid-cooled 4-stroke DOHC 4-valve engine is mounted in a highly rigid aluminium frame that ensures superb control when riding at high speed. Complementing advanced electronics that include Power Mode selection, KTRC (Kawasaki TRaction Control) and Launch Control Mode, Brembo front brake caliper and front master cylinder, adjustable handle and footpeg position, a hydraulic clutch and electric start are some of the features designed to help Kawasaki riders fight at the front of the pack. Neither championship allows engine or frame modifications, so the team elevates the KX450's base race-winning potential with suspension and intake/exhaust tuning.
