About the AMA Supercross / Motocross Championship

The AMA Supercross and Motocross Championships are American-based series recognised by the AMA (American Motorcyclist Association). AMA Supercross (AMA SX) races are held in 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 highly popular AMA-SX series, which draws crowds numbering in the tens of thousands, and the AMA MX championship are held in the U.S., they attract top riders from around the world. Alongside the World Motocross Championship, they represent the pinnacle of motocross racing.
Kawasaki competes in 450SX/MX with the Kawasaki Motors Corp., U.S.A. (KMC)-operated Monster Energy Kawasaki team, and in 250SX/MX with the KMC-supported Monster Energy Pro Circuit Kawasaki team.
Monster Energy Kawasaki’s ace rider Eli Tomac finally wins the the long-cherished AMA-SX title in 2020 after winning three consecutive titles since 2017 in the AMA MX championship.
Riding for the highly acclaimed Monster Energy Pro Circuit Kawasaki team last year, Adam Cianciarulo took the 2019 250MX title. With Cianciarulo stepping up to the 450 class and teaming up with Tomac this year, the team welcomes two new freshmen to take on the AMA-SX and AMA-MX championships.

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. Launch Control Mode, adjustable handle and footpeg position, a hydraulic clutch and electric start are some of its class-leading features. Neither championship allows engine or frame modifications, so the team elevates the KX450’s base race-winning potential with suspension and intake/exhaust tuning.

In the AMA Supercross and Motocross Championships, the Monster Energy Pro Circuit Kawasaki team competes with the KX250. Like every KX motocrosser since the debut of the brand in 1973, the KX250 was designed based on a “Built to Win” philosophy. With finger-follower valve actuation and the only dual injectors in the 250cc class, its engine delivers phenomenal high-rpm power. Launch Control Mode, which gives riders an edge for nailing the holeshot, and a large-diameter coil spring fork, which contributes to its superb high-speed controllability, are just some of the KX250’s other high performance features. The Monster Energy Pro Circuit Kawasaki updates the base model with their owns team-developed Pro Circuit tuning and aftermarket parts, further elevating the machine’s circuit prowess.
