Very sorry to hear this. Tough one.
My son is 25 and "surprised" me earlier this year by showing me his completion certificate for a motorcycle course. 3 days of training in a parking lot and you can bring your certificate down to the DMV and get your license.
He bought a used 800cc Suzuki as a starter bike and has been riding with me, slowly getting used to it and learning the ropes. I have to admit, I am very conflicted about my son riding a bike. I know this sounds hypocritical since I ride, but it's MY HIDE on the line, not his.
We live in metro NY (Long Island) and cagers are crazy here. They simply do not care. Recently someone passed us across a double yellow line because he was going too slow. He is being very conservative which is a good thing.
It's tough when it's your kid. Love the sport, but people in cars are crazy and you are taking a knife to a gunfight on a bike.
