Don't know if anyone can answer this or not but I bought one of these off eBay and the strap whips against my neck, and it hurts....like hell. It has a funny little plastic piece on the end like its supposed to clip into something but there is nothing I can see if clip into.

Love the helmet otherwise. I get little to no buffeting which is amazing imo, it weighs nothing and its way more sound proof than my HJC. When all the vents are open on top (front and back) I can feel the wind whistle accross the top of my head. Also it has a little lever on the visor to crack the visor a tad to help with defogging.

 

Clips onto the square d-ring

 

jschmidt to the rescue again. I found a manual, your right.
