His contributions to the sport earned him the moniker "The Fastest Man on the Planet."

Since discontinuing racing in 2016 and formally retiring from professional racing in 2019, Stewart remained relatively quiet in the industry, until returning to the sport as an on-camera commentator for the AMA Motocross and Supercross championships in 2022.
