Seth Hammaker

Seth Hammaker is chasing what was taken from him in 2025 — the 250SX East championship. He ran Cole Davies to the wire, won two main events, and finished second in the standings. That close finish fuels the 2026 campaign with a specific, earned motivation: he has been there, he knows what it takes, and he is coming back to finish the job.

From Bainbridge, Pennsylvania — the Susquehanna River country, Dutch Country Pennsylvania — Hammaker grew up in a state not known for supercross factories, but one that has produced hard-working, technically precise racers. He earned 250SX Rookie of the Year honors in 2021 and has steadily improved each season under the guidance of the Pro Circuit program and Mitch Payton.

The Pro Circuit Program

Mitch Payton's Pro Circuit Kawasaki operation has delivered over 306 combined wins and 31 championships in AMA Supercross and Motocross. That history means every rider who comes through the program has access to accumulated championship wisdom that no other team in the 250 class can match. Hammaker is the product of that system, and in 2026 he's ready to bring another title to Foothill Ranch.

Bainbridge to the Championship

After Round 15 Philadelphia, Hammaker sits second in the 250SX East standings with 180 points — 26 behind champion Cole Davies. The 250SX East season is complete — Davies clinched the title at Philadelphia. Hammaker finishes runner-up for the second consecutive year. He has proven he can win races and close championships. The Bainbridge Kid will be back.
