RK MXU Sealed Motocross 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. RKs MXU 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. RKs 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. RKs UW seals also feature small contact points to reduce cold start drag. UW ring thickness is 50% thinner than O-ring with longer life time. MXU is currently available in 520 pitch. GB520MXU Sealed Motocross Chain weighs a mere 3.04 lbs per 100 links making MXU the lightest sealed off-road chain on the market.
