Haiden Deegan Re-Signs with Monster Energy Yamaha Star Racing: 250SX in Supercross, Full-Time 450 Debut in Pro Motocross 2026
The speculation is over—Haiden Deegan has officially re-signed with Monster Energy Yamaha Star Racing in a multi-year deal that outlines a bold path forward in his already impressive career. The announcement confirms that the second-generation motocross star will remain in the 250SX class for the 2026 Monster Energy AMA Supercross season before making a highly anticipated move to the 450cc division for the AMA Pro Motocross Championship and SuperMotocross World Championship (SMX) Playoffs.
Deegan, the 2024 250SX East Champion, is expected to line up in the 250SX West Region for Supercross next season, potentially allowing him to run the coveted #1 plate. With unfinished business and titles still to chase in the 250SX class, the move offers a final chance for dominance before entering the sport’s premier class.
The shift to the 450 class for Pro Motocross and SMX marks a major milestone in Deegan’s young but decorated career. Known for his aggressive riding style and high race IQ, Deegan will join a deep and competitive 450 field, including current points leader Jett Lawrence. The matchup has fans buzzing, as Deegan’s raw speed and growing maturity could make him an immediate contender against the sport’s elite.
This long-term commitment from Yamaha Star Racing signals continued faith in Deegan’s potential to become a franchise rider at the highest level. With full factory backing, a top-tier team, and a clear path ahead, 2026 is shaping up to be a defining year in Deegan’s career.
