Yeah, I agree whokilledkenny, the reason I asked the question is that today's 600's like the ZX6R, R6, GSXR600, Honda 600RR are very much on par with yesterday's 1000's and 1100's which were classified as Superbikes, and today's 1000's like the ZX10R, R1 etc. are on par with yesterday's Hypersports like the Busa (ouch!!, now I am going to get it!)
Yes I know the 600's are called supersports, but in the light of above, can they not now also be referred to as "Superbikes". They are all "Super"!!
