Is the new GSXR1000 faster than a Hayabusa in a straight line? 145 in the quarter is very impressive. We all know on a roadcourse which is faster. I have a buddy who turbocharged his Hayabusa and it is fast!!
Sportrider Magazine last tested the Hayabusa in 2002 and had a 1/4 mile run at 10.237 @ 140.54.
However, at the time the Hayabusa was made there were grumblings in Japan that if the motorcycle manufacturers did not control the power of their motorcycles than the government would. There was supposed to be a gentleman's agreement amongst the manufacturers to regulate their own industry. It has been suggested that the Hayabusa was detuned and restricted not to break 200 mph. That agreement has gone to the wayside since, as the capabilities of today's sportbike are quite exceptional. This is just information that I have read and could be wrong. I would have to say that your friend's Hayabusa is probable much, much quicker.
I started a new thread as this was off topic from that other listing.
