RK introduces out new 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.
Maximum CC rating: 500.
9.000 Lbs/Ft Tensile Strength. Gold Inner and Outer Plates.
