MATRIS

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