This kit is particularly aimed at riders restoring or maintaining vintage roadsters — notably the KAWASAKI Z 900 (years 1974–1976) — who want a robust product that is easy to install and maintain. The presence of O-rings limits internal lubrication loss, while the lightweight design helps reduce unsprung mass without sacrificing mechanical integrity as specified by EK.
Ensure proper installation and adjustment (tension and lubrication) to optimize the lifespan of the kit on your motorcycle.
