Shock Absorber Type 642 Competition Active Wear Outfits, Fitness Women, Health Fitness, Beautiful Women. The ultimate in motorcycle shock absorbers: the upper mount is a precision milled component that connects to the compression reservoir and houses the high and low speed compression adjusters. With 22 clicks each, they can be dialed precisely to your needs. A pressure relief valve prevents hydraulic lock at maximum compression speed and mitigates uncontrolled jolts. Rebound is externally adjustable in 22 clicks, and spring preload is steplessly variable. Product may vary from picture.
