Motorcycle Fork Seals & Bushes

Teknik Fork Seals & Bushes

Fork Seals & Bushes

Motorbike front forks need regular servicing to replace wear parts - especially the seals & bushings that sit between the upper & lower fork casing tubes. We sell combined seal & wiper kits, inner & outer bushing kits, matching pairs of bushes or seals, or just an individual seal or wiper so you only ever buy only what you need; they come from a range of OEM suspension manufacturers plus reputable aftermarket performance brands. If you are a competent DIY garage tuner check our complete fork rebuild kits, or note Teknik Motorsport offers a 3 month warranty on the fork seals we install at our workshop. For mud scrapers and tube protection see Fork Performance Parts, for maintenance advice Pressure wash them properly and for installation tools try our fork seal driver kit.

Maintain sealing, slide precision and fork life

  • Prevent oil leaks with correctly fitted oil seals and avoid metal-on-metal damage
  • Keep dirt out with dust seals and wipers to protect chromed inner tubes
  • Restore tube concentricity with inner (slide/piston) and outer (guide) bush kits
  • Buy single parts, matching pairs or full kits from OEM and performance brands

Recommended Pairings

Consider matching your replacement seals and bushes with Suspension Tools for accurate installation and longer service life.
