MATRIS

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