Matris Fork Conversions



Original equipment motorcycle forks are by their very nature a compromise. They are set up by the manufacturer for the average rider of average weight and ability riding on the average road!! Unfortunately, since people, their weight, riding ability and the roads and tracks they ride upon are not average this means that by their very nature the forks and their settings are always wrong and can be vastly improved upon.

Manufactured in the Italy to the highest quality, Matris fork conversion kits are designed to improve upon the original equipment and can be set up much more accurately for each individual rider. Depending upon specification, this means they will improve upon both the springing and damping effects making the forks more precise, more adjustable, easier to use and ultimately better in every regard. They are available in three principal formats, Spring Kits, Hydraulic Kits and Complete Cartridge kits.

All aluminium components are made from 7075 aluminum, lapped and hard anodised. Linear springs are Cr-Mb alloy steel with cataphoris surface treatment and are available in different rates for different bike models and different rider weights.
