Having a racing back ground, seat belts are standard operating procedure!
As for helmets, I feel that it is a good idea to wear a helmet at all times. I don't think the minimal brain buckets that are available should qualify as a helmets. My former next door neighbor (older biker) had gone down on his Harley with one of those little helmets and broke his face and junked his brain enough that he is now in an assisted living facility because he can't take care of himself. The worst part is I know he owned a full face helmet that would have saved his way of life!
Werd!
My sister works for a motorcycle supply store, mostly Harley type stuff. The badboys always go in there looking to get a helmet andthey all want one of those worthless "scull caps" which IMO you might as well be wearing a condom

, She trys to talk them into a touring type helmet, a guy came into the store last year and gave her a hug and told her that she saved his life. He was riding his Road King in a rural area on a Sunday and came around a corner where a little import car came around in his lane clipping the left side of the bike, he flew off the bike and into two walnut trees. He didn't walk away, but there were no head injuries, the helmet was destroyed, but intact.
BTW, she said it was a Simpson Touring pro with the interchangible inserts for comfort, like a $580 hat.
I have lost several freinds to motorcycle helmet and seat belt issues, I'm not willing to put my life on the line to look like an idiot..check that, cool...
My whole family depends on me making it home...
