RK 420MXZ4 or 428MXZ4 Non O-ring Chain (130 link)

The newly released 420MXZ4 and 428MXZ4 lightweight mini-works racing chains were developed from the same advanced alloy material and manufacturing technology as 520MXZ4. These mini-works racing chains are the strongest in their class, giving you the best Value-Performance rating of any MX Racing Chain in the world today!

This heavy-duty chain was designed for the serious Motocross racer. MXZ4 chains feature Chromoly steel construction with seamless rollers and bushing plus they feature oversized special alloy pins for added strength. All components are heat-treated using RK's exclusive HIT (Heat Induction Transfer) process. 

These new MXZ4 chains are far superior to RK's standard MXZ420/428 chain. These chains are the longest lasting 420/428 chains currently available on the market. We stock them both in 130 link which should accommodate any model mini-bike for the little shredder in your life. Used and endorsed by the DDC Racing Mini-Team.
