Motorcycle Fork Compression Free Piston Inner Shaft Seals

Teknik Fork Free Piston Shaft Seal

Fork Free Piston Shaft Seal

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. A free piston slides on a threaded hollow centre rod with outer o-rings & bushes; these genuine factory KYB & Showa shaft seals stop oil or gas transfer. For small parts see Fork Adjuster Parts or upgrade options like clicker knobs, billet free pistons and revalving kits.

Sealing and damping integrity for fork free pistons

  • Prevent oil passing the floating piston and avoid loss of compression damping
  • Keep gas charge sealed in pneumatic forks and maintain consistent clicker response
  • Protect o-rings & bushes to extend fork life and reduce service frequency
  • Ensure compatibility with KYB and Showa top caps, springs and valving assemblies

Recommended Pairings

Consider matching seals with Suspension Tools for installation and service.
