Description
A worn or damaged piston directly limits your YFZ350 Banshee’s RPM capability, throttle response, and overall engine longevity. The Wiseco PK142 kit restores factory compression and sealing while its high-silicone forged construction handles sustained high-load riding without degradation. This is a complete top-end solution—no hunting for individual components.
