the 99-02 manual says to use "Unleaded gasoline only". So if you are putting 91 in your 99-02 you are wasting money.

the 03+ says to use 91 octane or higher unleaded gasoline. so its your call if you want to listen to a bunch of lawyers about wht is best for your motorcycle.

Damn, i didnt think anyone would get it right... 02 and older dont waste your money, 03 and newer use 91. SO SAYS THE MANUAL... Which may or may not be true. Unless you have certain mods done you will get nothing out of higher octane fuel. Most of the time... you can do timing tricks for a temp. hp boost. But thats a horse of another color.
