Fork oil is not just fork oil! Developed within our Wilbers-BMW- Racing IDM Superbike team. Next to this new quality you can now have the proven Wilbers fork springs for the very best fork spring kit! Once there was the twin-tube damping system where simple drillings were responsible for the oils flow speed thus creating damping. Today we have very modern cartridges, both closed and open! The modern telescopic fork, most of the time is equipped with shim regulated piston, needs special quality fork oil! Often this oil has nothing in common with oil supplied by nonsuspension-experts! Our motorsport-activities with BMW in the IDM Superbike offer us the means and knowledge to further improve existing products to your benefit.
