I own an SA2005 rated G-Force full faced helmet, had it fit at the local speed shop by the wife of the owner. She has 20+ years of experience in properly fitting helmets. I originally was going for a Bell M3, but decided that the G Force fit me just a little better. Again, find a shop that has been around for a really long time, one that the road racers and circle track guys flock to for parts and service.....
