My first MC was a VCG 1962 Honda Dream 305. I loved it. In retrospect, it was kinda sorry, but it was already a near Classic when I was riding it in the middle 1970s. I rode it for about 2 years or so. This was long before the Harley rage and lots of folks talked to me about it. Nowadays they would say, Ohhh What's that?" look closer, see it's not a Harley, sniff, and walk away (no BS! they do that to my 650!) A couple people asked me if it was a Beemer, even (the 62 Honda, not the Savage).
But I digress.
One day my youngest brother wanted to ride it. He just turned 16. I made him promise to go to the end of the street and come back and to take it easy since he'd never ridden "real iron" before. I also insisted he wear my helmet.
He went down the street, around a curve and off out of site. When I said to the end of the street, I meant to the end of the block. He interpreted it a little more literally.
A few moments later, he phoned me from about a mile away to inform me he "bought" my bike. He had his first experience a curve at speed and discovered counter-steering the hard way.
He was about 1/8 roadrash all over. He ground a 4" diameter hole in my Bell R/T fiberglass helmet, which saved his life. He looked about as bad off as that girl in post #1.
I took him to the hospital where I said he fell off a bicycle. They were suspicious with all his raw skin, and he still had it together enough to say he was holding onto a car fender when he lost control at high speed which made it more plausable. (We always were creative liars

)
The lie saved my parents a lot of $$$ since if he was illegally operating a motor vehicle the insurance company would not pay, as well as other legal issues, needless to say, my parents emotions were mixed, glad he was OK, mad I let him ride my bike, glad we were good liars, mad we deceived the hospital, glad they didn't have to pay out of pocket, etc. .

Kinda proud but not.
Anyway he spent a large amount of the next month or so waiting for scabs to fall off.
He and I both agreed he was danged lucky I made him wear the helmet.
