Haiden Deegan Bio
Haiden Deegan (born January 10, 2006) is an American professional motorcycle racer competing in the AMA Supercross and AMA Motocross championships. He rides for Monster Energy Yamaha Star Racing and has quickly built a reputation as one of the most promising young talents in American dirt bike racing. By the age of 19, he had already collected major titles in supercross, motocross, and the post-season SuperMotocross World Championship.
Early Life and Background
Haiden Deegan was born in Temecula, California, where he was raised in a deeply motorsports-oriented family. From an early age, he was exposed to motorcycle culture through his father, Brian Deegan, a founder of the Metal Mulisha freestyle motocross team and an influential figure in action sports. That environment gave Haiden a natural starting point, and he began riding motorcycles at a young age.
His early training was shaped by both family influence and the broader Southern California motocross scene. Surrounded by riders, mechanics, and event culture, he developed foundational skills that would later support a smooth move into national-level competition.
Path to Professional Racing
Deegan built his résumé through the AMA Amateur National Motocross Championship at Loretta Lynn’s Ranch, where he won seven titles across various youth classes. He spent most of his amateur career racing on KTM, and at just 10 years old, he landed a backflip on a 65cc bike, a moment that signaled his comfort with high-level risks. In 2021, he signed with the Monster Energy Star Yamaha Racing team, setting the stage for his professional transition.

He developed within manufacturer-supported programs and youth rider development systems, gaining the consistency needed for the professional ranks. His signing with Monster Energy Star Yamaha Racing in 2021 marked the final step of his amateur progression.
2023 AMA Supercross Debut
Deegan made his professional debut in the 250SX class of the 2023 AMA Supercross Championship. In his first main event appearance, at round four inside NRG Stadium in Houston, Texas, he placed fourth. He continued to qualify for mains throughout the season and earned three podium finishes, ending the year second in the final 250SX West Region point standings. That performance earned him the 2023 250SX Rookie of the Year award.
2023 AMA Pro Motocross
Transitioning to the outdoor 2023 AMA Pro Motocross Championship, Deegan continued his strong form in the 250 class. He captured his first overall victory at the RedBud National and added a second win at Washougal. He consistently finished inside the top ten and closed the season fourth in the overall 250 standings with 371 points.
2024 AMA Supercross
In 2024, Deegan continued with Yamaha Star Racing and shifted to the 250SX East Region. He claimed his first career 250SX victory at round seven in Arlington, Texas, and added wins at rounds 13 and 17. He finished the season second in the East Region standings behind Tom Vialle, reinforcing his place among the top 250 prospects in the sport.
2024 AMA Pro Motocross Championship
Deegan dominated the 2024 AMA Pro Motocross 250 class, clinching the overall series title with five moto victories across the season. The championship confirmed his arrival as a top-tier professional. He was later slated to represent Team USA at the 2024 Motocross of Nations alongside Chase Sexton and Aaron Plessinger, but he chose to step aside and focus on healing from a wrist injury.
Monster Energy Yamaha Star Racing Era (2025)
For the 2025 season, Deegan switched from the 250SX East Region to the 250SX West Region. The change paid off, as he clinched the 250SX West Region title at the 16th round inside Empower Field at Mile High in Denver, Colorado, adding the AMA Supercross 250cc West Championship to his résumé.
SuperMotocross World Championship
Deegan has also excelled in the SuperMotocross World Championship, the post-season series that combines supercross and motocross formats. He has won both 250 SMX championships since the event was introduced in 2023, cementing his status as a complete rider across all three major American series.
Driving Style and Strengths
Deegan is known for aggressive early-race speed, strong starts, and the ability to adapt between tight supercross layouts and high-speed outdoor motocross tracks. His technical growth at Monster Energy Yamaha Star Racing has been paired with a confident, attacking race craft that suits both stadium and natural-terrain racing.
Notable Races and Milestones
Signature moments include his first 250SX victory in Arlington, his 2024 AMA Pro Motocross 250 title run with five wins, his first outdoor overall at RedBud, and the 2025 250SX West Region clincher in Denver. He also landed a backflip on a 65cc motorcycle at age 10, an early-career highlight that previewed his fearlessness.

Haiden Deegan Family
Family Background and Racing Lineage
Haiden is the son of Brian Deegan, a founder of the Metal Mulisha freestyle motocross team and a well-known figure in action sports and short-course off-road racing. He is the younger brother of Hailie Deegan, a NASCAR driver, and the older brother of Hudson, nicknamed Huckson, who races in the Supermini class.
Personal Life
Deegan continues to be based in the United States, growing up in Temecula, California, where he first learned to ride. His family remains closely tied to motocross, with his younger brother also pursuing a competitive career in youth racing.
2025 Season Performance
Haiden Deegan’s 2025 campaign has been defined by his move from the 250SX East Region to the 250SX West Region. The switch produced immediate results, as he battled at the front of the field each week and built a comfortable points lead heading into the late rounds of the schedule.
He clinched the 2025 AMA Supercross 250cc West Region title at the 16th round inside Empower Field at Mile High in Denver, Colorado, adding another major trophy to his young career. The title followed his 2024 AMA Pro Motocross 250 championship and his 2024 250SX East Region runner-up finish, showing continued growth with Monster Energy Yamaha Star Racing.
With the supercross title secured, Deegan is positioned to defend his 250 motocross crown later in 2025 and to pursue another 250 SMX title in the post-season. He remains one of the headline names in the 250 class and a strong candidate to graduate to 450-class competition in the near future.
