Just tried Shoei's fitting guide...
1) With the helmet on and the chin strap fastened, shake your head side to side. If the helmet moves independently of your head then the helmet is too big. The helmet lining and cheek pads should be in direct contact with your skin. While shaking your head, your skin should move with the helmet.
Unsure, there is movement. If I hold the helmet, I can rotate my head inside, with helmet staying fixed.
2) Place one hand on he back of the helmet and push forward. Use your other hand and try to slip your little finger between your forehead and the helmet lining through the visor aperture. If there is room for more than just the tip of your finger, the helmet is too big.
Fail - Can get my whole little finger in this gap, it can touch the top of the lid.
3) Lastly, place one hand on the chin bar and push up (while the chin strap is secured), if the helmet comes off your head, it is too big. Next, place one hand on the back and push up again, if the helmet rolls off of your head, it is too big.
Fail on this too, top part of the lid does lift off my head, so that it's no longer in contact with my head.
You are right, new lid me thinks
