RK MXU Sealed MX Chain

When conditions turn muddy, sandy, wet, or if riders just want a long lasting racing chain, the MXU sealed chain is just for you. The ultra-thin UW-seals are perfect for bikes with narrow clearance and delivers triple the life expectancy when compared to a non-sealed chain.

RK's UW-Ring seals utilize triple barrier grease protection plus anti-debris technology. Anti-debris protection is vitally important to maximize chain wear life by eliminating debris friction between internal components. UW seals feature small contact points to reduce cold start drag.
