1-16 GENERAL INFORMATION
Technical Information - PSF (Pneumatic Spring Fork) Front Fork (KX450FD ∼)
Spring Characteristics Adjustment
Previously, changing to an optional spring needed complicated disassembly. As for PSF, spring
characteristics can be changed by simply changing air pressure.
Compared to the conventional front fork, PSF has a wider adjustable range of spring characteristics.
For air charging, a commercially available hand air pump can be used. For air pressure adjustment,
a tire air pressure gauge can be used.
Oil change becomes easier since the main spring is eliminated.
3) Inner Structure
New oil (KHL15-11) is used as operating oil.
