The fork valve changes the flow of oil into the fork in both directions and the fork spring causes more constant spring behavior. With the handlebar cover, you can fine-tune the fork spring preload again - turning the adjusting screw increases the pressure and thus the fork spring preload. YSS offers this vehicle specific kit throughout the set.
