Used for many MX style swingarm setups depending on gearing. Be sure to count your links so you don't end up short.

RK’s MXZ4 chains are made for supercross and motocross racing. MXZ4 chains feature chromoly steel construction with seamless rollers and bushing. RK’s Chromized pins drastically improve the wear resistance more than two times compared to normal non-sealed chains while absorbing shock loads from extreme jumps. All components are heat treated using RK’s exclusive HIT (Heat Induction Transfer) process. 420MXZ4 has a maximum tensile strength rated at 4,980 lbs and is suitable for professional level racing. This is the same chain that we run on our Factory race bikes.
