Phew!!! Coming from 600cc's, I've never felt the power nor thought of the power a Busa can have, compared to a 600cc. I've been riding my Busa for a few weeks now since it has gotten warmer here in Minnesota and boy, did I have an exhilarating experience! The first time I did this on my Busa, I wasn't ready. I was at 60 MPH and downshifted (gently by rev-matching) to 2nd gear and applied about 80-90% throttle and punched it up to about red-line and I got a head-rush when I let off of the throttle and up-shifted to 3rd gear! Maybe it was because of the long winter and no riding for a while or something but I don't remember feeling this with any 600cc sport bike! It felt like there was so much geforce that I wasn't used to or ready for it or something and the sensation felt like a "head-rush." It was a great feeling though. I'm loving this bike's power!!!
