Fork cartridge Matris F20K for BMW F 800 GS Adventure 13-17 (fork type WP) / (the kit keeps the original spring set)

F20K, the “asymmetrical” cartridge
The kit is supplied with specific high sliding fluid.
The cartridge kit is supplied ready to fit, no modification to the original fork is required for the assembly. It is fully reversibile.
The F20K is an asymmetrical, 20 mm diameter, hydraulic cartridge kit that replaces completely all the existing fork internals to upgrade the forks that already have some level of adjustment as standard.
Fully adjustable on spring Preload and feature separate asymmetrical Compression and Rebound adjustment, the cartridge is provided using the innovative “quad-valve system” that avoids the risk of fluid cavitation.
It allows an excellent hydraulic damping upgrade and a great set-up.
Ideal for sport, naked and adventure bikes, on race, track and street use.
Every adjustment click makes a difference to the damping and can change the needed setting.
All components are made from Alu alloy with oxidation surface treatment to ensure long wear life.
The springs can be changed quikly without removing the forks from the bike
