A high-performance cartridge kit is the ultimate upgrade you can make to your stock forks. By replacing the OEM cartridge assembly with purpose-built internals, amazing levels of traction and control can be achieved. Aftermarket cartridges are Supersport / Superstock legal in most road racing organizations, and are used by just about every factory & privateer rider competing at the professional level.

While very good results can be achieved by revalving the stock cartridges, cartridge kits generally offer better performance combined with ease of installation. If you can replace your fork seals, you can install a cartridge kit, and enjoy the benefits of remarkably improved handling right out of the box.
