Motorcycle Fork Compression Piston Base Towers

Teknik Compression Base Tower / Post

Compression Base Tower / Post

If your motorbike has modern "Separate Function Forks" you will often find a comp adjustment clicker on one top cap and rebound on the other, but many adjustable designs fit compression damping adjusters to both caps. Learn about open or closed chamber front forks in our open or closed chamber article. Adjuster assemblies are compact but complex, with a top cap sealed against the fork tube with an o-ring, a clicker assembly and bleed screw inside, and a threaded hollow centre rod. At the bottom, comp valving parts are locked onto base valve posts with a locknut; connecting push rods, free pistons and the Inner Chamber Spring control initial plushness. If you need small parts or upgrades see our Fork Adjuster Parts, clicker knobs, free pistons and revalving kits.

Compression base towers for damper valving

  • Secure shim stacks and washers to the damping piston on the base valve post
  • Allow compression clicker adjustments to alter oil flow via the push rod
  • Replace worn or damaged posts to restore factory damping geometry
  • Provide a mounting point for revalving and performance upgrades

Recommended Pairings

Consider matching with Suspension Tools for accurate assembly and tuning.
