Motorcycle Fork Lower Oil Lock Cases

Teknik Oil Lock Case / Bottoming Cone

Older bikes had chrome steel pipe clamped in the triple trees, sliding inside the aluminium outer case at the bottom, with it's cast in axle clamps. This is a "Conventional" front fork & is still used on many retro cruisers - but most road or offroad sport bikes now use it's successor - "Up-Side Down" forks. USD Fork Legs have larger alloy upper tubes clamped at the top, chromed lower leg pipes sliding inside, with a separate pair of lugs at the bottom as the feet that clamp the front axle.

Between an axle holder foot & inner tube is often an internal oil lock case assembly to keep it liquid tight & free of leaks. These bottom cones can also hold the fork's compression bump rubber, but other seals, spacers & the rebound adjustment bolt can be found in our Axle Lug Internals section - find out how to use that adjuster effectively in our clicker setup guide.
