Description
Sealed Motocross racing chain.
Designed and developed for Supercross and Motocross applications under tough racing conditions. The MXU utilizes RK’s advanced ‘U’-ring for superior sealing and longevity. Real world testing proved that this chain is very durable and dyno testing proved that horsepower is maximized and lap times consistent with non sealed racing chains. The MXU was built super narrow to run on almost any motorcycle and keep the weight to a minimum. This chain is super strong with all the specifications you expect from an RK racing chain and the future will prove that RK has the sealed ring technology to run with non sealed racing chains most are accustomed to.
