I read a bunch of posts on here and decided to try the AFX-39 helmet. I usually wear a large helmet, but after the advice here I tried a medium AFX.
When it arrived, I opened the box and hoped for the best. Well, it fit ok but it seemed a bit tight. I can deal with that, the foam will probably break in a bit, but it also seems a bit short (top to bottom and front to back). Luckily, my neighbor was looking for a helmet and he bought it from me.
I think I will order the Fly Trekker in large and see what happens.
Buncha dirt bikes with license plates.
