You've adjusted pressure, compression, rebound, played with different volume spacers or springs, and nothing fixed it. That's because every one of those adjustments is downstream of the real problem. Tight or out-of-round bushings create a significant increase in both static, and dynamic friction that your fork has to overcome to move. No spring setting or damper tune fixes friction, if you've ever run your rebound adjuster wide open and still felt a harsh fork on repetitive hits, that's bushing friction, not a damper tune problem. The RMS burnishing tool permanently corrects bushing geometry removing stiction and friction in about ten minutes. You'll feel the difference before you get to the end of the driveway. Used in all shops from the garage to the professionals. The bushing sizing standard the industry has adopted. "This is the last piece of the puzzle! I could have skipped the upgrades if I only knew this tool earlier." — Verified buyer
