I bought a big 4 wheeler last year. I had bought a helmet about 3 or 4 months before I bought the 4 wheeler. Took a few photos of it still on the trailer the night I brought it home, with a matching helmet sitting on the seat. Sent the photos to a few friends that night. One repliied telling me I was a sissy for wearing a helmet on one if them. Well, after going down a small hill, getting thrown off my ride and having all 600 pounds of it tumbling down the hill and landing on the side of my head was not exactly fun. A friend was at the top of the hill watching. He shouted and asked if I was O.K. I said yes. Got up, flipped my ride back on it's feet, looked it over and said,"Thank GOD for helmets. This thing just paid for it's self. It's worth every penny I paid for it. They can call me a sissy all they want to." Had it not been for a helmet that day, I'm sure I would have been severly injured or killed. I'd rather be a live chicken than a dead duck. And yes, I wear a helmet on my motored bike, along with other armor.
