Motorcycle Fork Leg Bare Outer Tubes

Teknik Fork Outer Tubes

Fork Outer Tubes

Older bikes had chrome steel pipe clamped in the triple trees, sliding inside the aluminium outer case at the bottom, with its cast in axle clamps. This is a "Conventional" front fork and is still used on many retro cruisers, while most road or offroad sport bikes now use the successor "Up-Side Down" forks with larger alloy uppers and chromed inner tubes. These OEM fork outer guide cylinders are sold individually and come empty inside & out, without spacer washers, retaining clips or boots - all sold separately in our Outer Tube Parts.

Fork outer tubes: replacement, upgrade and race-ready cases

  • Direct replacements for Conventional or USD forks on classic, road and offroad models
  • Available in stock silver alloy or performance coatings such as Titanium Nitride (TiN) and Kashima hard anodizing
  • Sold empty to suit custom spacer, clip and boot choices during service or rebuild
  • Use with separate lower-leg service parts and axle feet for correct fitment and damping

Please remember that whatever finish your tubes have, they need regular care — see our bike maintenance guide and protectors in outer tube protectors & covers. We also stock axle lug kits fork axle lug sets, holeshot clamps holeshot clamps and a clicker setup article clicker setup guide.
