RK has supplied MX chains to all major Japanese manufacturers of motorcycles for over 40 years, and distributes its chains both to the MotoGP and MXGP teams.

The quality GXO is a chain designed to withstand the harshest conditions. They offer the best properties under extreme conditions and protect against abrasion, heat build-up and loss of lubricant, and help to keep dirt and dust away, maintaining better chain lubrication.

The shape of the XW-rings is the most optimal for keeping a chain lubricated under the most extreme conditions and maximises its service life.
