Derek Kelley grew up in Riverside, California — a region where motocross is woven into daily life. The Inland Empire has produced generations of professional riders, and Kelley's development gave him the technical foundation that Pro Circuit Kawasaki identified when they brought him into their factory program.
Ninth in the 250SX East championship with 74 points represents consistent performance throughout the East season. Pro Circuit Kawasaki demands results, and Kelley has delivered steady points-scoring while continuing to develop the championship-level speed the iconic green program expects.
"Pro Circuit has developed so many champions. I want to be the next one."

Pro Circuit Kawasaki fields factory-spec machines in both the 250 and 450 classes of AMA Supercross and Pro Motocross. The Husqvarna brand traces its racing roots to the Swedish forests of the 1960s, and the current program represents the modern expression of that racing heritage — with full KTM Group engineering backing and Rockstar Energy as the title sponsor.
