Ships from our supplier in 2-3 business days, at your door in about a week.

RK's MXZ4 is a non-sealed chain made for supercross and motocross racing. It uses chromoly steel construction with seamless rollers and bushings; RK's chromized pins improve wear resistance more than twofold over normal non-sealed chains while absorbing the shock loads of extreme jumps, and every component is heat treated with RK's HIT process.

RK does not recommend it for street use.
