Description
The piston is the heart of your engine’s combustion cycle—wear, scoring, or improper tolerances kill power and reliability. This PROX kit delivers OEM-equivalent precision for the Kawasaki KX250/KX250X, ensuring proper ring sealing, minimal blowby, and consistent performance whether you’re racing or trail riding.
