RK 520MXU UW-Ring Chain (120 link)
- Fits all models of the Alta lineup.
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. They have a maximum tensile strength of 8,000 foot pounds, but weigh just a mere 3.21 lbs! (per 100 links) They can handle any MX, SX or off-road race application from 125cc to 500cc displacement. Many professional off-road race teams such as Factory FMF KTM and Factory Rockstar Husqvarna use this chain.
