A multi-time winner in the U.S., best known for his fearless, aggressive style, big-race mentality, and larger-than-life personality, Deegan has built a reputation that’s propelled him to the top of the sport. Fans know him as “Danger Boy” for his bold race craft and high-intensity performances. Now, for the very first time, he’s taking that reputation to the world stage – and he’s chosen World Supercross as the battleground.
