Motorcycle Fork Compression Piston Base Towers

If your motorbike has modern "Separate Function Forks", you probably have a comp adjustment clicker on one top cap & reb on the other, but for many adjustable designs both caps have compression damping adjusters - learn more about open or closed chamber front forks. If you've never adjusted your dampers, read our clickers article - they're like opening or closing a tap for more or less suspension oil to flow.

Adjuster assemblies are compact but complex, with a top cap sealed against the fork tube with an o-ring, a clicker assembly & bleed screw inside, and threaded hollow centre rod screwed underneath.

At the bottom end are the comp valving parts locked onto one of these base valve posts - the specific set of shims & washers assembled either side of the damping piston are held onto the "tower" using a locknut.
