RK 520MXU UW-Ring Chain (120 link)

MXU is the lightest sealed-ring motocross chain available on the market today! RK designed these chains for the "weight conscious" professional motocross racer. The 520MXU is the next generation of motocross and off-road racing chains; they feature RK's new UW-sealing ring technology. MXU chains are designed to provide the most consistent power delivery and increased chain life. All components are heat treated using Rk's exclusive HIT (Heat Induction Transfer) process.
