Bike of the Month | Justin Perkin's 2026 Vision F1

At just 17 years old, Justin Perkins, better known as DR. J, is already one of the tallest, smoothest, and most composed riders lining up in Expert. Hailing from Glendale, Arizona, Justin has been riding BMX for an impressive 14 years.

Standing at 6’2”, Justin brings a powerful yet relaxed riding style that matches his approach to Supercross: ride hard, keep it fun, and don’t let pressure get in the way. 

Coached by Corey Reid, Justin draws inspiration from riders like Jack Davis, Bubba Harris, and Corey himself. Off the bike, you’ll find him in the gym, or blasting Red Hot Chili Peppers.
