MXZ Series Transmission Chain RK — Manufacturer ref. 420MXZ-110-CL
Designed for Enduro and Cross use, this reinforced 420 chain from the MXZ series by RK is aimed at riders who put their transmission to the test on demanding terrains. Non-O version (without O-rings), it relies on a robust carbon alloy steel structure to ensure a reliable connection between the sprocket and the crown during accelerations, jumps, and muddy trajectories.
This MXZ Series chain is designed to withstand the demands of professional motocross while remaining easy to install and tension. Its natural steel appearance integrates easily with the running gear of 125–150 cm³ machines. Ideal for those seeking a solid transmission that is easy to replace and suited for off-road conditions.
