Got a G-force V9 helmet, but I can't figure out the chin strap. I can't figure out a way to adjust it when the helmet is on my head. The instructions I got were kind of generic and G-force only talked to me on the phone. I was wondering if someone has one and can snap a picture of how the strap is suppose to be? I would really appreciate it.

Also, I assume the chin strap is necessary for car drag racing or do you not need it if in a car? Thanks.

 

Is that a dirtbike helmet?
