PD Valve
Outer Diameter: 0.9 inches (23.8 mm)
Manufacturer Part Number: 118-4002
JAN Code: 4589641181782
Remarks:
The inner valve gives the front fork that does not have a dampening adjustment function to the damper rod, giving the "flexibility" and "hip" like a cartridge fork.
If the outer diameter to inner diameter size of the fork spring fits the outside diameter of the PD valve, it can be set between the fork spring and the damper rod for any vehicle.
Note:
PD valve body height and fork spring preload increase
The orifice of the damper rod is required.
Depending on the top shape of the piston rod, the production of an adapter is required.
