Hey Heraclid
I, too am looking into bikes. I have only riden once in my life on a 250 cc. It was scary., I am taking an MSF class and then buying a bike. I have been looking at the "hayabusa" . Everyone has been agaisnt it as not a good 1st bike . So now I am leaning towards the SV, at least for a year.
If I feel comfortable I may just go for the busa.
Like you, I am not one to take speeds lightly, I respect the power, its just I love the look and meanness of the Busa.
I believe I am a very careful, scared driver
