Matris Cartridge F25R Range Yamaha Yzf R1 04-06

Matris has developed the F25R kit for all super and hypersport motorcycles as well as maxi naked bikes for track and road-oriented use. Very close in philosophy to the F20K kits, the F25R kits differ in the larger size of the components. Like all Matris kits, installation is easy and reversible without any modifications to the original fork.
The Matris F20K kit is fully adjustable in spring preload, compression, and rebound. The springs are calibrated to the rider's weight, and you will need to provide this information when placing your order.

This kit will allow you to configure your motorcycle as you wish with a wide range of adjustments and incredible efficiency, the F25R being designed for racing use under very high demands.

The complete cartridge kit consists of the following elements:
- Cartridge cylinder D.25 mm made of Al 7075 alloy with anti-friction treatment and anodized honing.
- Specific springs depending on your use and the rider's weight (to be provided to the Starshop-moto team when you place your order)
- Pumping rod D.12 mm made of Al 7075 alloy with anti-friction honing and hard oxidation treatment.
- Complete set of compression and extension pistons D.25 mm machined from solid Al 7075 alloy supported on self-lubricating smooth bearings and complete with specific valve assemblies for total control of hydraulic flows.
- Anti-cavitation valve assembly.
- Compression adjustment valves at the fork bottom if originally provided.
- Specific oil provided (Motorex)

The various possible adjustments are as follows:
- Spring preload, mounted on axial roller bearings, with reference clicks (range 15 mm).
- Rebound, with reference clicks (range of 38 clicks).
- Compression, with reference clicks (range of 38 clicks).
