Haiden Deegan

Haiden Deegan is 20 years old. He has two AMA championships. He clinched the 2026 250SX West title at Round 10 — the youngest in recent memory to claim back-to-back indoor and outdoor titles. He is Danger Boy, son of Metal Mulisha founder Brian Deegan, and he has already outrun every timeline anyone projected for him.

Born on January 10, 2006 in Temecula, California, Deegan grew up in a family that treats motorsport the way other families treat going to the park. His father is Brian Deegan. His sister Hailie Deegan is a professional stock car racer. His brother Hudson is a professional FMX athlete. Haiden became the youngest person ever to execute a dirt bike backflip at age 10, then set about making every other amateur in the country look at him as the kid they needed to beat.

The Deegan Brand

The Deegan family brand is one of the strongest in action sports, and Haiden has built his own lane within it. The DNGR / Danger Boy apparel line at shopdeegan38.com carries his signature gear. His personal site dangerboydeegan.com tracks news, schedule, and sponsors. His social media following dwarfs every other 250SX rider in the field.

Champion at 20

The 2026 250SX West title is Deegan's second major AMA championship — and he's still 20 years old. The 250MX title in 2024. The 250SX West in 2024. Back-to-back 250SX West in 2026. The question everyone is starting to ask is: when does he make the jump to the 450? The answer, whenever it comes, will be interesting.
