Well, I've had this Symax 3 helmet on the road for about 1,500 miles this year and I don't think I can use it anymore. I've run into two large hurdles. The first is that it aggravates my forehead. They use a perforated padding instead of a smooth padding that doesn't move at all which causes it to grip and rub which ends up feeling like a sunburn after 30 minutes. The other is the extremely narrow field of vision. Compared to my HJC AC-12, its considerably smaller. I can no longer see the gauges without moving my head and have reduced side vision.
Has anyone modified the inside of a helmet with a Dremel? I'm thinking if I remove some of that foam padding with a sanding bit, it might reduce the pressure and make it work. Nothing can be done for the field of vision problem.
