    The GB520MXU RK Chain is a narrow and ultra-light sealed MX/SX racing chain. This chain is the lightest sealed-ring motocross chain available on the market today! Made for the professional motocross racer, 520MXU is the next generation of motocross racing chains featuring RK's new UW-sealing rings. 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. The GB520MXU can be used for both off-road and Supercross events. Many professional off-road race teams from FMF KTM Factory Off-Road to Rockstar Husqvarna Factory Off-Road use the MXU. This chain will last 10 times longer than a traditional motocross non-o ring chain!
