seriously- i don't know 4 sure. as you can see i'm 60 years old and not in real good shape. the busa is the most awesome, powerful bike i've ever rode and i've been riding for well over 40 years. i am not a sport bike rider (come from harley world). i know i don't ride the busa to 1/2 it's potential. i hate to admit this but a much better younger in shape rider beat me to the top of cheaha mt on an 1100 yamaha maxim! that's embarassing. i can go like hell in a straight line but when i get above 130 i start backing off. guess i'm just getting old- i don't even like fast cars anymore. was thinking of selling the busa & getting a softail for my 2 wheeler. i still have the electraglide w/sidecar for touring. but i met some wonderful people here and good friends. we shall see. i think i'm giving her away but i don't want the harley shop to get her on trade.
