YSS Premium R18 Shock Absorber B-Stock

Original YSS shock absorber, developed for the BMW R18.
The length of the shock is as standard, it replaces the standard shock 1 on 1.

This shock absorber improves the standard behavior of the bike in a very positive way. It is more comfortable, gives the rider a more solid feeling and is safer in use because the Nitrogen supported damping system is very effective and adjustable.

YSS shock absorbers have a very wide range of use compared to other brands, so solo use for lighter riders or duo use with 2 somewhat heavier riders is no problem, this all fits within the adjustment range. (tools are included)

- This shock is serviceable.
