RK Racing Chains have been chosen by more FIM World Championship teams and AMA World Superbike/Super-Sport Teams than any other chain in the past 25 years! RK's "RX-Ring" chains feature an X-Ring shaped seal. Viewed in cross-section, the X-Ring has two lubrication pools and seal points versus the single seal point/pool design of a regular O-ring chain. RX-Ring technology offers less torsional friction, increased high-stress performance, and a 30% longer wear life compared to standard O-ring chains.
