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 handling of their motorcycle.
The design incorporates an adjustable preload system via threading, allowing the spring tension to be adapted according to the load or riding style, and then locked in place. The result: a simple installation to restore suspension behaviour — absorbing irregularities, providing support in corners, 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 during installation to ensure fitment on your motorcycle.
