What is replaced internally when you install our cartridge kit

Marzocchi 2012 888 CR Stock Internals

Shown to the right is the 2012 888 CR left leg Damper assembly. Internal chamber semi-sealed damper with pressure spring design. (meaning the oil is self leveling due to bleed hole in the pressure spring chamber)
Adjustable compression bleed with shimmed compression valve.
Adjustable low speed bleed plastic rebound valve with a simple check valve.

Pros: new inverted semi-sealed design, retains shimmed compression valve.

Cons: Seals for pressure spring piston and rebound rod need maintenance
no shimmed rebound piston
no midvalves
no ABS for bottoming control
many plastic parts that may wear out and leave particles in internal oil
and valving
