Restore proper engine sealing with Namura NA-10001R piston rings, designed specifically for use with compatible Namura pistons. This replacement ring set is honed for a precise fit and supports consistent compression, efficient combustion, and reliable oil control when installed in an engine using the matching 85.97 mm piston application.
Manufactured for Namura piston systems, these rings are intended for powersports and small-engine applications where dependable performance and accurate component matching are essential. The honed finish helps promote proper ring-to-cylinder seating during break-in when the cylinder preparation, piston, and installation procedures meet the applicable manufacturer requirements.
Fitment: For Namura pistons requiring an 85.97 mm piston ring set. Verify piston model, cylinder specifications, ring configuration, and engine application before ordering. Namura NA-10001R is intended for Namura pistons only and should not be substituted for rings designed for another piston brand or profile.
Install the rings according to the engine service manual, including orientation, end-gap inspection, and break-in procedures. Proper fitment and installation are necessary for maintaining compression, minimizing oil consumption, and supporting long-term engine reliability.
