Motorcycle Fork Bare Top Caps

Fork Top Cap Incomplete

If your motorbike has modern "Separate Function Forks" you may see a comp adjustment clicker on one top cap and rebound on the other, though many adjustable designs use compression damping adjusters on both caps. Learn about open or closed chamber front forks at our technical article on chamber separation, and read damper basics in our clickers article. These Showa top caps come empty without internals — they seal with an o-ring and feature a clicker, access port and either an emulsion bleed bolt for oil forks or a Schrader valve for air forks (use a hand pump from our fork air pumps). The centre shaft, free piston, inner chamber spring and comp valving piston stacks are sold separately; see fork adjuster parts, clicker knobs and free pistons.

Top caps for compression damping and inner chamber tuning

• Replace visible top cap housings for Showa and similar adjustable forks
• Maintain emulsion bleed bolts or Schrader valves for oil or air forks
• Fit empty caps before installing centre shafts, free pistons and valving stacks
• Enable use of clickers, ICS springs and comp pistons to tune initial plushness

Recommended Pairings

Consider matching with Suspension Tools for installation and air pump maintenance.
