Fork casing tubes are kept concentric by split metal ring bushing sets on Up-Side Down Forks; the inner (or slide or piston) bush has a dark coating of teflon on the outside surface to slide easily, and fits over a groove at the top of your thinner hard chromed tube, while the outer (or guide) bush has a lining of teflon on the inside surface, and fits into a groove at the base of your larger aluminium alloy tube.

Motorbike front forks need regular servicing to replace worn parts and these guide bushing pairs are no different. We carry a range of brands; our own Teknik sets, genuine OEM parts from KYB & Showa suspension and performance aftermarket parts from Innteck.
If you need more than just the guide bushes when rebuilding your fork legs we recommend you check out our complete fork rebuild kits to save time & money.
