2021 Supercross Calendar

The Monster Energy AMA Supercross Championship is the world's most prestigious indoor off-road motorcycle racing series, held in major stadiums across North America from January through May. Unlike its outdoor counterpart, Motocross, Supercross takes place on man-made tracks featuring massive triple jumps, punishing "whoop" sections, and tight rhythm lanes that demand extreme technical precision and physical agility. The series is divided into two primary categories: the premier 450SX class and the regional 250SX (East and West) classes, both utilizing high-performance four-stroke machinery. Regulated by the AMA the championship features a high-energy format of heat races and "Main Events," where the world’s elite riders compete under stadium lights for the ultimate title in front of tens of thousands of fans.
