Oh, she got hurt bad all right. At the very least scarred for life. Ladies, do not go screwing around on you idiot boyfriend's crotch rocket wearing a tanktop...
Yup, broken wrists or ribs probably. Not to mention the road-rash. Her skin will never look the same again.
On a guy, scars aren't a problem as much. I like my scars. Scars on girls does not look nice and I'm sure that 99% of them would agree with that.
That guy is a fool for putting his girlfriend at risk like that. I'd have to seriously consider even taking my girlfriend on a bike, let alone hot-dogging like that.
She is an idiot for going on a bike without a jacket but he is a bigger idiot for going along with it.
If I took her on a bike it'd be a proper bike too, not some Japanese rubbish. We'd be out for a cruise on chopper of some sort. That's how you ride.
