Motorcycle Fork Leg Bare Inner Tubes

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.

We sell complete inner tube assemblies, but these OEM KYB & Showa fork inner tubes are sold individually and come empty inside & out, without seals, bottoming cone or axle lug. Depending on your suspension tuning budget, they come in stock chrome finishes, or with performance coatings like Diamond-Like Carbon (DLC) or the wild rainbow colours from Physical Vapor Deposition (PVD).

Please remember that whatever slick finish your inner or outer tubes have, they still need to be kept clean & maintained - dried gritty mud can scratch and kill even the toughest coating eventually - use our outer tube protectors & covers to help.

If you still want a performance edge, remember that we also have factory racing kit axle lugs for a range of specific forks, or universal holeshot clamps to give an advantage off the line to most offroad motorcycles.

We also sell all the separate stock retaining clips, spacer washers, set screws, clamping bolts, sealing o-rings & oil lock cases ready to fit to a matching factory axle holder foot when you service your bike's front suspension. The centre sealing bolt at the base of the feet often features rebound adjustment - find out how to use that adjuster effectively in our clicker setup guide.
