At Denver's Mile High Stadium this past Saturday, Hawaiʻi native Grant Harlan earned a season-best finish of ninth place in the 450 main.

​

Harlan, who calls Kailua-Kona home, despite being listed as from Justin, Texas, races for the Rock River Yamaha team, a privateer-support team in the sport of Supercross. Supercross is a motorcycle racing sport where dirt bike athletes compete on man-made tracks that range from 45 seconds to one minute or more in football or baseball venues around the continental United States.

​

Harlan, who has been a professional racer since 2020, has one career top-5 finish. He took fifth place at the Indianapolis 2 Supercross in the 250 main aboard a Honda CRF250R on Feb. 5, 2021. His fifth place is the best finish by a Hawaiʻi-born racer since former pro racer John DeSoto won at Delta Motorsport Park in Delta, Ohio in July 1973.

​

Harlan will race in the final round of the 2023 Monster Energy AMA Supercross Championship at Salt Lake City's Rice-Eccles Stadium to conclude his season. The 2023 Lucas Oil Pro Motocross Championship and 2023 SuperMotocross series this Fall remain in question.
