Matris KTM RC8 25mm Sealed Fork Cartridge Kit - Gas Charged


Product Description

The Matris 25mm Sealed Gas-Charged Cartidge kit completely replaces the OEM fork internals with NO modification needed. The OEM KTM RC8 fork is a bit out dated by Superbike standards and leaves much to be desired by way of tuning. Matris 25mm F25SA Sealed Gas-Charged Cartridge kit will give your RC8 a significant improvement in handling and control. Designed, machined and assembled in Italy using high quality materials and featuring the beautiful craftsmanship you would expect from Italian craftsmanship, these drop-in cartridges from Matris are second to none. 

Benefits of the F25SA gas charged cartridge kit over the F12R kit: A sealed gas charged system allows for more bottoming resistance without having to run an extremely stiff fork setup. Think Gas Charged System at the bottom of the cartridge like a pillow that when the forks are pushed to their limits, it allows them to ride very low in the stroke without a harsh/stiff bottomed out feeling. 

Due to this items custom nature, please allow 1-4 weeks build time
