HIGH SPEED & PERFORMANCE RK’s GXW series are the top of the line Road Race and Superbike chains, offering the best in high-speed and extreme heat performance. The leading edge XW-Ring seal is made of an advanced Nitrile Butadiene composite and features three contact lips and two convex inner/outer stabilizers. This means three lubrication pools to protect against high-speed abrasion, heat build up, torsional flex and the loss of lubricant under these extreme conditions.

As a result GXW chains provide the user with up to 10 times longer wear life compared to standard chains. GXW chain seals are compression and distortion resistant to provide the ultimate in rotating efficiency.

Looking for an affordable, long lasting performance chain? Look no further, RK’s XSO chains offer less torsional friction and increased high-stress, high-speed performance providing a longer lasting chain at an affordable price. All RX-Ring chains have “X” shaped seals and improved metallurgy giving you 7 times longer wearlife than standard O-ring chains. Viewed in cross-section, the RX-ring has two lubrication pools and contact lips versus the single contact design of a standard O-ring chain. Giving the chain a longer life gives you more value for your money.
