If you are modifying your Harley® for increased horsepower or aggressive riding, S&S Cycle's Moly faced piston rings can be a good choice. The Moly coating material provides excellent friction reduction properties and can withstand high temperatures better than many other ring coatings, making it suitable for high-performance engines. The porous nature of the Moly coating helps to hold oil on the ring face, providing better lubrication during initial engine start-up and under heavy load. Moly rings often break-in more easily than other types of rings due to their coating properties. Even for everyday riding, Moly rings can offer improved engine longevity if you frequently push your bike hard. Order the Moly faced piston rings designed for your HD® model's engine type.
