RK CHAINS 428XSO X 118 CHAIN
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.
