MXU UW-Sealed Motocross Chain
RK GB520MXU SEALED MOTOCROSS RACE CHAIN
When conditions turn muddy, sandy, wet, or if riders just want a long lasting racing chain, RK offers a sealed supercross, motocross and off-road racing chain called MXU.
RK’s GB520MXU features ultra-thin UW-seals which is 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. RK’s UW seals also feature small contact points to reduce cold start drag. UW ring thickness is 43% thinner than O-ring with longer life time. GB520MXU weighs a mere 3.04 lbs per 100 links making MXU the lightest sealed off-road chain on the market.
