Yes. It's a good 2 stroke and reliable. I'm 13 and I've got a big wheel Yamaha yz85. I think you might need a small wheel unless your big. If it's your first bike you'll be okay because it's not overly powerful.
Yamaha XT250
a 120cc dirt bike is suitable for a 17 year old

A Yamaha 125
a xr 100
Yes, but good luck fitting on it ;)
