I think everyone else has given the positive side. Has you're dad simply said no or has he given his reasons he doesn't think you should get a motorcycle? If he hasn't explained, ask him to sit down and discuss it and you have to actually listen. He may have some very good reasons for you not to get one right now and, if you listen, you might agree. I have my own bike, enjoy riding, and give a thumbs up to all other responsible and safe riders. That said, I hope he lets you get one.
