I have a very tight Shoei X-11 that I really like. I also have very large ears that I have to unfold every time I put on my helmet. It's not the cheapest helmet around and so the thought of moving the chin strap made me nervous that I would ruin my helmet. However, in my situation the bladder was sitting on top of the chin strap. When I mentioned this to the owner (Al) of the Quiet Ride Muffs, he suggested me moving them and gave me instructions on how to do the operation. First, I went out and purchased stainless steel rivets, but that isn't necessary. I used stainless because it is exposed to the weather and I feel that stainless is stronger. When the cheek pad is removed, it exposes the inner helmet shell with the metal chin strap connector that would be under the ear muff. Al suggested that I grind off the rivet holding the metal connection and relocate the metal chin strap connection piece lower and forward of the original whole. I used a rotary tool to do this. With the metal chin strap connection piece removed from under the ear muff the ear muff will be about 1/4" closer to the helmet shell on each side. This will give you another half inch distance between ear muffs. This will make it more comfortable to take the helmet on and off. I used short 3/16" pop rivets to reinstall metal chin strap in new location. It was actually easy to do and only took about a half hour to do complete. I think I stressed way too much about this. If this is something that you are not comfortable with and you are worried about your helmet warranty or your safety, then I would pass on this part of the instructions. IMHO, after doing this project, I feel the strap is more secure than it was in the first place. The rivets I used were stronger than the original rivets, being that I used stainless. Also, with the original installation of the straps, the rivets didn't go all the way through the helmet, mine do. I believe that Shoei didn't want the rivets showing for appearance sake. I don't feel that take away from the look, though. If anyone wants pictures of the rivet installation, let me know. I know some of you may feel that this isn't worth it, but I would do over again heartbeat. As a matter of fact, when I purchase my next helmet, it will be the first thing I do, unless they are already installed.
