Wildomar, California sits at the center of the Southern California supercross ecosystem — training facilities, factory teams, and amateur programs all within a short drive. Mitchell Harrison grew up immersed in that environment and turned professional in 2020 with the building blocks of a serious 450 career.
Harrison's 2026 season aboard the Monster Energy Kawasaki KX 450 has produced 67 points and 19th in the standings. For a rider at his stage of development, the focus is on accumulating experience in the premier class against the best 450 riders in the world every Saturday night.
"Every weekend I learn something new. The 450 class is a different world and I'm getting better every race."
