Yes, it can be very dangerous if you go into thinking that you're invincible and nothing can hurt you. If you don't take a safety course, don't wear a helmet, and have no clue what you are doing, it can be very very dangerous. Tell your parents that it's dangerous, but you'll wear all of the safety gear (Helmet, goggles, boots, knee pads, chest protector, etc.) Find somebody in your area who is willing to show you the ropes. Don't go into thinking that it's going to be easy or anything like that. Also, go down to your local motorcycle shop and ask them about riding and what you'll need to get started and they'll help you out. One last thing, don' think that it's going to be cheap. The bike will be anywhere from 2,000 to 6,000 dollars. Then all of the safety gear can run from $500 all the way to over $1,000. Good luck.
