Description

Manufactured to the highest standards to outperform the competition, Wiseco 4-stroke piston rings maximize your performance and keep you firing on all cylinders. These rings are crafted from various metals and with specific finishes for both street and track. Designed to underscore piston lubrication, reduce bore friction, and optimize the heart of your engine, Wiseco rings improve the overall function of your pistons and powerplant. The 4-stroke rings are intended for use in cast iron, NikaSil, boron composite, and electrofusion bores; certain rings are designed for limited coatings, such as the XJ with chrome bores and the XN with NikaSil bores. Match up the specs from your motorcycle with the size and type of piston ring replacements you need. You can always depend on race-proven Wiseco technology!
