This is RK's high-tech GXW chain with newly developed XW rings!
Modern, high-powered motorcycles subject chains to extreme levels of stress. For maximum resistance against these strains, RK has created special XW rings to keep lubricant sealed in while shutting out dirt and dust.
RK's chains are designed to withstand the toughest conditions. They are resistant to high-speed abrasion, overheating, torsional flex and lubricant burn-out.
An XW ring shap is optimal for keeping the chain lubricated in extreme conditions, and can increase the service life of your chain considerably. The lifespan of an XW-ring chain is 50% longer than that of an O-ring chain!
Supplied with clip.
