F20K hydraulic fork cartridge kit

Conventional and inverted suspension choices

Italian suspension specialist Matris is offering a hydraulic fork cartridge kit that completely replaces all the existing fork internals in conventional front fork set-ups.
The F20K is a D.20 mm hydraulic cartridge, with a 12 mm piston rod in aluminium alloy, with anti-friction lapping and oxidation surface treatment.
Fitted with a hydraulic flow control dedicated shim stack, the anti-cavitation billet aluminium, surface anodised, CNC-machined quad valves are configured in an asymmetrical system – with compression adjustment in one leg, rebound in the other, and spring preload in both legs.
It will fit on all original forks equipped with original adjustable or non-adjustable cartridges without modifications for a fully serviceable, fully reversible installation.
The fork kit is supplied with a set-up specific fluid and a set of linear springs in Si-Cr alloy steel, available in different rates, specifically for different bike models and the rider’s weight for a totally custom suspension install.
Also seen here for inverted (USD/upside down) forks, the F43SP is a complete pressurised fork (for the most popular 600 and 1000cc models) that is equipped with Matris’ internal F25 sealed and pressurised cartridge system.

F43SP pressurised fork

Available in standard chromed, gold (TIN/Titanium Nitride treatment) or full black (DLC/Diamond Like Carbon treatment), the 43 mm chromed steel inner tube installs in a 50/54 or 50/55 mm black oxide treated aluminium alloy outer tube with a fork lower CNC-machined from a solid billet of aluminium alloy with 100 or 108 mm radial caliper bracket.
Features include compression, rebound and spring preload adjustment, with “Speed Sensitive System” damping that responds to the damping speed of the advanced hydraulic sealed and pressurised cartridge.
