RK XSO Series: Designed for Basic Motorcycle Models, lighten chain weight while securing adequate strength required, emphasizes light feeling of acceleration.


Features RX-Ring that have “X” shaped seals and improved metallurgy giving you 2 times longer wear life than standard O-Ring chains.


The 428XSO is equipped with unique X-Ring technology. Doubling the sealing surfaces results in a significantly better seal, preventing dirt, water, and other contaminants from penetrating inner components. This reduces friction and results in extended service and wear life (up to 30% longer than an O-ring chain and up to 80% longer than a standard range). All RK chains are made of high-carbon alloy steel for strength and durability.
