The Matris FKS spring kit consists of two springs available in different stiffness (depending on the rider's use and weight) and two spacers, as well as a specific oil can. These kits install without modification on your motorcycle.
This kit allows you to make your roadster or touring bike more enjoyable and performant at a lower cost, limiting the bottoming-out phenomena that are too present on certain motorcycles from the factory.
The FKS fork kits are composed of the following elements:
- Springs (depending on the rider's use and weight)
- Aluminum spacer ·
- Specific oil can included
The higher range than the FKS kit is the FKE kit, which additionally allows you to adjust the spring preload thanks to an adjustable cap, and features a flow diverter (hydraulic brake).
