Assuming rain may keep me from cutting 3 acres of grass this weekend I have a backup project that's long overdue.
My daily riding helmet - Arai SZ Ram III
Problem defined - the liner has nothing covering the ears. There is simply no liner nor padding over the ears. Arai left this area open to the polystyrene shell. Of course your ears are untouched and very comfortable but provides no noise baffling. Earplugs help but it can be improved on. I also speculate Arai left the area open to accommodate headsets, as is often the norm for riders who would use this helmet (most likely seen on Goldwings).
Goal - to custom cut formed blocks of cushioning to fit in the open areas. Cover these shaped blocks with a comfortable material and friction fit/velcro them in place. They are not structural in any way no moreso than the cushioned liner is to begin with. Also plan on creating a small pocket to hold the earpiece speaker of the inbound bluetooth enabled cellphone / passenger intercom.
Will take detailed pictures and report back successes or failures.
from the pictures the speaker appears to be about the size of another speaker I already have and can use for reference. Figure I can fashion a small pocket for the speaker to insert at the left ear by shaving that padding foam down by the approx depth of the speaker.
Going to use a "spongy" foam for the core, not looking for anything rigid as the styrene base.
The liner is removeable and I did a little searching first but couldn't find anything from Arai to address the problem. Figured I'd just do it myself if I can't find a better answer.
Schuberth has some great features and the C2 was on my short list of helmets but the moment I put it on and closed the face it felt like my eyeballs were popping out of my head. Most uncomfortable helmet I've ever tried on. Loved the features but the fit was a deal killer.
