Ride JBI's Review of the KYB PSF 2 Fork
The KYB PSF 2 is a cheaper and simpler production air fork that KYB used to replace the KYB PSF 1 air fork, which became the base for the KYB A Kit Air Fork.  Using an open cartridge design with a balance spring KYB created a very simple but decent air fork.  However poor valving and mid valve piston design result in a fork that could be much better.
