1 st Wreck, 1976 on a Kawasaki H-1, Shoei full face helmet. I slid in a curve due to salt and sand accumulation. Flew over a five foot bank and landed skidding on my face. One Shoei full faced helmet completely destroyed, one rider walked away with a minor abrasion on left palm. 1978 on a KZ 900, some three quarter helmet. Went into a left hand curve, high rate of speed, kickstand left down. Bike was thrown into a ditch I was thrown onto the road on my back. When I got through scouring down the road most of the skin on my back and upper arms was removed, just had on a long sleeve shirt. The back of the helmet looked like someone had taken a belt sander with 50 Grit paper and gone from one ear to the other across the back. I do not think the back of my skull would have survived that one. Just procured a bicycle riding helmet the other day, I chose a Bell Super 2 Mountain Bike Helmet to use for mild road use. The sales attendant was arguing with me about not needing the extra protection, she lost the aurgument.
