For over 40 years, RK has produced top-class chains for all of the major Japanese motorcycle manufacturers, MXGP and MotoGP teams!
RK's XSO chains are some of the best X-ring chains on the market! The Z1 version is even more durable than the original XSO.
X-ring seals help preserve lubricant while shutting out dirt, dust and other harmful debris, effectively minimising friction to increase the service life of your chain. Chains with X-ring seals last 30% longer than O-ring chains and up to 80% longer than standard chains. They also roll more smoothly!
