Motorcycle Fork Cartridge Cylinder Complete Assemblies

An internal damping cartridge cylinder sits in the middle of the outer case tubes inside most oil filled motorbike front forks. The suspension fluid can either be shared with the rest of the fork leg, or can be separately sealed - read more in our Closed vs Open Chamber Forks technical article.

These complete pre-assembled OEM KYB & Showa cartridges are ready to install, but we also sell all the individual servicing parts separately, such as naked cartridge insert pipes, top & bottom seal case heads, their internal rubber rod seals, plus the outer fork spring collars & parts.

But if factory isn't good enough, you can mod your bike with our performance billet coil spring perches or go all the way with a set of DIY drop in adjustable fork cartridges for the racing edge.

Many cartridge forks come with compression & rebound adjusters built in to fine tune your damping for different terrain - if you've never had a go, read our clickers guide to get more out of your riding for free.
