Deegan Stays at Star Racing

Deegan Re-Signs with Monster Energy Yamaha Star Racing

Monster Energy Yamaha Star Racing’s Haiden Deegan to join the 450 team in 2026

MARIETTA, Ga. – Monster Energy Yamaha Star Racing is pleased to announce a multi-year deal with Haiden Deegan that will see him continue with their championship-winning program. The Californian has enjoyed success aboard the team’s YZ250F – going from a title-winning A-class amateur to a multi-time champion in the pro ranks – and looks to continue that success next year as he embarks on his rookie season aboard the YZ450F. In 2026, he will join the 450 team, starting the year off by making another Monster Energy AMA Supercross 250SX title run under the 450 tent, and then launching his premier class title campaign with them in Pro Motocross and the SMX World Championship Finals.

Since joining the team’s amateur program in the fall of 2021, Deegan has been a proven title contender, winning multiple national titles and going on to enjoy a stellar pro debut season with Rookie of the Year honors in both supercross and motocross, and his first 250SMX title. In just three years, the 19-year-old has amassed an impressive number of titles and race wins aboard the team’s YZ250F. In addition to earning back-to-back 250SMX titles (2023-2024), he secured the 2024 Pro Motocross 250MX Championship and the 2025 250SX West Championship a round early. He currently has seven 250SX wins, 12 250MX overall wins, and three 250SMX wins.

With three rounds remaining of the outdoor season before the SuperMotocross World Championship Finals, it’s already been a storied season for Deegan. After sealing the deal on his first 250SX title with four wins and a total of nine podium finishes, he went on to launch a formidable title defense outdoors. The reigning 250MX and 250SMX Champion has earned five overall victories and 10 moto wins thus far, giving him a comfortable 45-point lead in the 250MX Championship and a 103-point lead in the 250SMX Combined Points. As the 2025 season comes to a close, Deegan has his sights set on securing the crown in both championships to cap off a successful tenure with the 250 team.
