Motorcycle Fork Axle Lug Internal Parts

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.

An axle holder foot holds these internals safe inside, like a large diameter oil lock spacer, washer & o-ring to keep the case liquid tight & free of leaks, a tough grub screw to secure the inner tube, bolts to torque the axle, a centre sealing bolt where you can drain the fork oil or which can hold the rebound adjustment - find out how to use that adjuster effectively in our clicker setup guide.
