Ya 177 is BS. Ive broek 180 in only medium length runs more than once. The RR is a slug. Them Brit's are on crack. the r1 isnt the fastest as you said allways, its slightly better on the track but that is subjective. Some riders might be better on th e ZX10. Ive seen 4 of them this weekend here at the Kentucky Derby area. Still no CBR though. I was on one 5 weeks ago so I know they are around. Perhaps no one wants one...
