I am just looking at it compared to my GRXR 100. Pretty similar set up. No rubber shield from the frame to the head. No foil shield under the tank. I can see a need for the foil under the tank. But I'm not sure about the rubber one. I really think it's more for water and dirt. I'll never ride this when it's wet. I'd like to leave the rubber one out. But would also like to hear from someone that already has with no issues.
