Garrett Marchbanks was born on August 23, 2002, in Coalville, Utah — a small town of about 1,500 people in Summit County, sitting in the mountains northeast of Salt Lake City. He began his professional career in 2019 with Monster Energy Pro Circuit Kawasaki — the same program that has produced champions for decades — and in 2020 won the Daytona 250SX main event, the most prestigious single event on the 250 calendar. His career since has been a story of persistence: program changes, injuries, team transitions, and through it all, a consistent ability to post results when the moment requires them.
His 2025 outdoor season was his clearest statement of what he can do. Third overall in the 250MX class, including his first career 250MX overall podium at the Washougal National — a result that came after years of near-misses and interrupted seasons. That performance earned him the opportunity that was always the goal: a factory 450SX ride with Monster Energy Kawasaki alongside two-time champion Chase Sexton.
"Joining Monster Energy Kawasaki is an amazing opportunity, and I'm really looking forward to this new chapter. The team has already made me feel very supported."
— Garrett Marchbanks · Monster Energy KawasakiThe 450 Debut Season
The 450SX class is a different sport from the 250 class — not just faster, but heavier, more physical, and with a depth of talent that allows for no gaps in preparation or execution. Marchbanks' first season alongside Sexton is an education in what championship-caliber professionalism looks like from the inside. Every round builds more data, more experience, and more pace. Coalville, Utah's finest is exactly where he needs to be.
Monster Energy Kawasaki — Team Green
Monster Energy Kawasaki's factory program carries 38 combined premier-class championships — a record that reflects six decades of racing commitment. The KX450SR is a works-specification race machine, and the partnership with Monster Energy provides elite marketing and athlete support. Marchbanks and Sexton give the team two distinct assets: proven championship speed and hungry developing talent in the premier class.
