Behind the team

Team story

The factory Kawasaki 450 program has been a fixture of the premier class for decades. Its 2026 lineup paired Chase Sexton with Garrett Marchbanks, who moved up from the separate Pro Circuit 250 organization. Sexton won two 450 Supercross main events during that season.

The team races the Kawasaki KX450SR across the SuperMotocross calendar. Its permanent identity is separate from Monster Energy Pro Circuit Kawasaki, even though the two organizations share a manufacturer and title sponsor.

Team management

Operator: Kawasaki Motors Corp., U.S.A. The official factory program is based in Southern California.

Achievements & milestones

Kawasaki's October 23 statement credits Sexton with two 450SX victories during their 2026 season together. Those results remain Kawasaki history after his departure.
