One of my friends got a sport bike right before graduation this past june, well he got in an accident on the highway the day before. Lets just say the left side of his upper body had no skin on it. and it wasnt the prettiest thing at a graduation. But they are fun. Wear somethin protective your first few times.
I think I would rather do bungee jumping before riding a motorcycle. The risks to me are just not worth it. Someone said it earlier and it wasn't the first time that I have heard this, but if you do decide to ride, you have got to act like no one (i.e. cars, trucks) can see you on the road.
I am thinking of getting a bike too, and I told my parents about it this summer. Ofcourse they weren't too thrilled...but eh. They live over seas....
