16 going on 17, eh? I'm glad to hear you're open to various alternatives, (besides the Hayabusa), that shows a good level maturity. Here's my suggestion. Look closely at the Yamaha XT225. It's a long way from a Busa for sure, but it has 10 good things going for it:
1. It's fun to drive.
2. The insurance is very reasonable.
3. It's excellent on gas.
4. It has an inexpensive purchase price. (~ $4K)
5. It's a good learning platform.
6. It allows you to ride off-road and practice your biking skills in the dirt.
7. It's light and easy to handle.
8. It provides good cheap transportation.
9. If (I mean when) you go down, parts are fairly inexpensive to replace.
... and most importantly...
10. It'll lessen your chance of getting hurt or killed before you develop the skill set you'll need to move on to a more powerful bike. Just like any other skill (math, music, foreign language, etc), it's a whole lot easier if you start at a lower difficultly level, then work your way up.
Young riders (or potential riders) pop up on this forum every month or so, basically asking the same question you did. Heed the warnings you're going to receive here. True, a few have successfully tamed the Busa as their first bike, but most honest riders will tell you, the odds where against them. In your case, not only are you new to biking, but you're new to driving, so you're taking on two major challenges; 1) learning to control the bike, 2) and learning skills to keep others from running over you. (And sometimes #2 is a lot harder than #1!)
Another suggestion. Search this forum for, "Busa as my first bike" (or similar wording), and read, read, read. There's a ton of good information to digest.
To help put your question in perspective; I've been riding since I was 12 years old (started with a Honda 50). Over the years I've ridden lot's of street and motorcross bikes; large and small. At 53 I consider myself to have an average skill level - but most riders with my level of experience will tell you, the Busa's awesome power can easily still scare the holly s### out of a person - and quickly kill them should they decide to disrespect it, or lose their concentration for a few seconds. Although its possible, IMHO, the Busa does not lend itself to beginners.
Nothing wrong with being a fan of a Busa though. Just be smart and work your way up to it. You'll enjoy it a lot more if you you do!
Good luck with your decision and welcome!
