Ok, first off...you need to be very careful with these machines, dood. They can really hurt you....as with any bike....really quick if you don't respect them. I would suggest getting a used one first. On top of that, take a MSF course and get some gear....you have much life ahead of you. Have you ridden before? If not, I would recommend getting a smaller bike. Not only will it be more forgiving, but your insurance rates will not be as high either. Getting a busa will skyrocket your insurance...
There's a thread here... lemme see if I can find the link.
Here it is. Read it with an open mind, bro. Again, remember that you have much life ahead of you....and the busa is an awesome machine that can really test your skills and your nerves.
