MATRIS

Fichier téléchargeable(Yamaha YZF R1 07-08)

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