The RK Racing Chain Series apply RK’s Ultra Thin UW Sealing rings.  UW-Rings, are 50% thinner than standard sealing rings which make it possible to design a sealed Chain with the similar weight to a Non-Sealed Chain.

RK Racing Chains are developed specifically for Track use and are not for Street Use. They are designed to be strong and light to ensure instant response on acceleration.  However the maximum chain life is approx 700km or less depending on usage.
