After market Foam insert for the Gatorz Radiator. This foam insert is great for helping to keep the wind and dust out while using your Gatorz Radiator motorcycle aluminum sunglass. This is not made by Gatorz, but it is made for the Gatorz Radiator. This part uses little hooks to attach to the frame so you don't have to permanently attach it with adhesive. It can be put on or removed as you please.
