The Matris F25R is a 25m Cartridge kit that completely replaces the OEM fork internals. The OEM KTM 890 fork leaves much to be desired by way of tuning, in fact, the stock fork does not allow for any tuning/adjustment what-so-ever. These drop-in cartridges from Matris are designed, machined and assembled in Italy using high quality materials and featuring the beautiful craftsmanship you would expect from the Italians.
This kit allows for more control of your oil flow over the 20mm cartridge kit and is able to handle the loads and forces of racing much better. This kit is focused towards the performance rider (racing or track day enthusiast) or anyone looking for the peak performance from their 890 Duke's front suspension.
