I am new to motorcycles so i had to get a new helmet. I'm stationed in Okinawa, Japan, so I don't have the luxury of just going to a bike shop and trying things on. I followed a video on sizing my head and bought an Icon Airmada helmet size medium. When it finally got here I immediately put it on. It is very snug and the cheek pads push on my cheeks very much. It's to the point where if I bite down too fast I will literally bite the inside of my cheeks. When I take the helmet it off I feel like I am squishing my head. Is the helmet too small or is my head just the wrong size for it?
