When the gate dropped on the 2026 Monster Energy AMA Supercross season in Anaheim, Cooper Webb lined up wearing the #1 plate. That number doesn't come for free. It comes from winning — and Webb has won three times in the 450SX class, adding the 2025 title to championships in 2019 and 2021. He is the defending champion. He is the measuring stick. And he is competing in a season that has already proven to be one of the tightest, most competitive in recent memory.

Born on February 27, 1996, in Newport, North Carolina, Webb grew up far from the training facilities and warm-weather tracks of California and Florida. He found his way to the top through sheer work ethic and mental toughness — qualities that define every championship he has won. His 2019 title came after a mid-season turnaround that shocked the paddock. His 2021 run was defined by consistency in a year when many riders were faster on any given night. His 2025 title closed out a campaign that saw him outlast a loaded field all the way to Salt Lake City.

"Defending is different from chasing. I've done both. Defending requires a different kind of discipline — knowing when to score points and when to hunt wins."

— Cooper Webb

The Star Yamaha Partnership

Webb races for Monster Energy Yamaha Star Racing — the program Bobby Reagan built from a privateer operation into the most decorated 250SX team in the sport's history, and now a 450SX championship machine. The Star Racing infrastructure — mechanics, data engineers, test riders, video analysis — is factory-level in every sense. The YZ450F is an updated machine for 2026, and Webb has spent the entire offseason adapting to its revised chassis.

Alongside teammates Justin Cooper (in his rookie 450 season) and Haiden Deegan (defending 250SX West champion), the Star Yamaha program is one of the most star-studded rosters in 450SX history. After Round 15 Philadelphia, Webb holds third place with 286 points — 24 behind championship leader Ken Roczen. With two rounds remaining, Webb's role remains clear: fight back to the front and make sure the #1 plate returns to his neck come Salt Lake City in May.
