RPM Fork Valves

This is the ultimate valve for the Yamaha FJ Damper Rod Forks. This is a true fork valve that convert the stock FJ forks into shim stack valves. The valves are design as a drop in for the FJ with minimal modifications unlike the other valves availble for the FJ. the stock fork springs will not work with this application, see chart in full descrition for the spring rate required based on weight.

Plus, the RPM fork valves are not just a cartridge installation, the are designed using patented Inertia Valve Technology.

The RPM fork valve sits on the top of your stock damper rod forcing through high quality deflection discs found intop of the line shock absorbers. But, when the front tire hits a bump the IVT circuit engages and the bump is quickly absorbed.
