YSS MZ456 Topline Z-Series Rear Shock Absorber — manufacturer reference MZ456-385TR-13-88. Designed for roadsters, this YSS rear shock absorber is aimed at riders looking for a reliable and easy-to-adjust replacement part to restore the original behavior of their motorcycle.
The design incorporates an adjustable preload system via threading, allowing the spring tension to be adapted according to load or riding style, and then locked in place. The result: a simple installation to restore suspension behavior — absorbing irregularities, providing support in curves, and maintaining rear end stability — without complex procedures.
Notable compatibilities: BMW R 850 GS ABS (0403) 1999-2000 and 850 cc variants. Check the length and mounting points to ensure fitment on your motorcycle.
