Description
When your CR85R’s top-end starts losing compression and throttle response, a quality rebuild kit is the difference between a seized engine and years of reliable performance. The Wiseco PK1216 gives you factory-spec pistons, rings, and gaskets in one complete package—eliminating the guesswork and compatibility issues of sourcing components separately. Whether you’re prepping for race season or restoring a trail bike to like-new condition, this kit delivers the precision fit and durability you need.
