I was just wondering how much movement there should be in the helmet when it's on your head...I put my lid on and gave my head a shake and there's about 5mm? of movement side to side. It doesn't shake around when I am just looking around, I just want to know if a little bit of movement is bad or not. I can feel the cheek pads on my face when I wear it for a bit, so that's a good so I've been told. I asked the bike shop if I can get thicker lining for it and they said I could...even though I really don't wanna have to. I got some "Bikers Club" brandname gloves and they fit....well, like a glove All that's left is the jacket, but that'll have to wait for a bit till I get rid of my debts. can anyone help? I wanna find out if I gotta return it. BTW it's a KBC helmet, LARGE size.
