RK 420MRU U Ring Chain - 110L

RK 420MRU and 428MRU2 Chains: Premium replacements for OE non-sealed chains, these feature RK's Ultra-Thin Seal technology, and U-Rings, allowing for a sealed chain with the width of a non-sealed chain. Ideal for daily-use vehicles and commuter motorcycles, they offer long-lasting durability.

RK 520MRU Chain: The lightest multipurpose sealed chain, designed for 125cc to 450cc applications. It excels in both street and track use, providing up to 15,000 km of chain life and optimal performance.
