RK's premium quality XW-ring is the ultimate high speed, extreme heat performance chain. The XW-ring is made of an advanced Nitrile Butadiene composite and is equipped with three contact lips and two convex outer stabilizers. This means three lubrication pools to protect against high speed abrasion, extreme heat build up, torsional flex and the loss of lubricant under these extreme conditions.
The "XW"-ring goes the distance to fully eliminate the risk of seal failure and provides the user with a 50% longer wear life than basic "O"-ring chain. The XW chain is not necessary for 600cc motorcycles due to the fact that tensile strength is far too high for any 600cc to exceed.
