This is a 3-piece set that includes a release fork COMP, bearing guide, and reinforced release hanger. It prevents the release bearing from running out of grease, maintains smooth movement, and maintains strength. To enhance this effect, it is treated with both WPC and DLC, which allows it to function smoothly over long periods of use, increases rigidity, and suppresses noise.
It is introduced on Ameblo's "M&M HONDA's Honda Honki."
