The AMA banned these fiberglass fork protectors because they have a leading edge and are somewhat aerodynamic. What picky people! These are shaped to fit Cerannis and Betors but they can be trimmed to fit most right side up dirt track styled forks. Made of paintable and repairable fiberglass. A nice finishing touch for your project. A great way to balance the color of your shock springs. You will have to grind the edges to fit the bumps on your forks. Use zip-ties or Velcro to mount. They are thin fiberglass and kinda snap fit on to sliders.
