RK MXZ4 WORKS RACE CHAINS

RK’s MXZ4 Supercross Racing chains are made for the serious supercross and motocross racer. 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. 520MXZ4 has a maximum tensile strength rated at 8,000 foot pounds and is suitable for professional level 125cc to 500cc class racing. MXZ4 technology is also available in 420 and 428 mini bike pitch sizes. 

2018 Supercorss Champions Jason Anderson and Zach Osborne both rely on RK’s racing chain GB520MXZ4.
