2021 AMA Supercross and Motocross Pro Numbers: List and Analysis

Supercross starts up in January, and it’s time to match the latest crop of riders to the numbers on their motorcycles. The biggest news for 2021 is that 250MX National Champion Dylan Ferrandis is sticking with #14 rather than taking advantage of the opportunity to run a single-digit number for the rest of his career. 450MX National Champion Zach Osborne made the same decision, keeping #16 as his permanent number. You won’t see 1W or 1E in the 250SX class—both Ferrandis and Sexton are moving up to the 450 class.

Currently, the only single-digit numbers available for the foreseeable future are #5 and #8. To earn a career single-digit number, you have to win a 450SX, 450MX, or 250MX title. A regional 250SX championship doesn’t get it done.

There are many noteworthy changes, starting in the late 20s:

  • Colt Nichols ditches unlucky #13 in favor of #64
  • Weston Peick surrenders #18 to Jett Lawrence
  • Alex Ray gets Jett Lawrence’s old #83
