Motorcycle Fork Top Cap Air Valves / Ports

Teknik Fork Air Valve / Screw

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 - sealed on the upper fork tube is a top cap with an o-ring, the clicker assembly inside. Also screwed into that cover will be one of these two types of port; if your forks run oil there will be an emulsion bleed bolt so you can drain out any frothy mess, or if your bike has air forks there will be a Schrader (tyre) valve so you can hand pump them to the right pressure. These ports need their own sealing o-ring, and a valve cap to keep gunk out of the gas stem core too.
