The Matris FKS spring kit consists of two springs available in different stiffness levels (depending on the rider's use and weight) and two spacers, as well as a specific oil can. These kits can be installed without any modifications on your motorcycle.
This kit allows for a lower cost to make your roadster or touring bike more enjoyable and more efficient, limiting the bottoming-out phenomena that are too prevalent on certain motorcycles from the factory.
The FKS fork kits include the following components:
- Springs (depending on the use and weight of the rider)
- Aluminum spacer ·
- Specific oil can included
The higher range above the FKS kit is the FKE kit, which additionally allows for adjusting the spring preload thanks to an adjustable cap, and features a flow diverter (hydraulic brake).
