Not to mention, why not a Mille? A Tuono is a Mille w. tall bars and no bodywork...no other changes. Don't get me wrong, I think the prev. gen 1000cc twins are a food fit in the C classes these days, but just having the Tuono in there is a mystery. A TL-R in superstock trim is no match for a 2nd gen Tuono, and neither is a SS RC51 or a SS SV1000, etc. Let 'em all in!
I'd leave them in HWT... Just be more traffic to contend with in the c classes. However, I agree that performance wise, there is no match. Yyou have to ride the hell out of TLR and an SV to keep up with the C bikes.
Which part are you disagreeing with? Is it the part that the other prev. generation twins are roughly equal to (or slower than) a Tuono, or the part where they'd be a fine fit in the C classes in SS trim? If it's the latter, I can tell you without a doubt that my 03 SS prepped R6 was faster around any track than the SS trim TLR that I have in my garage...never mind an 09 ZX-6 or whatever. If it's the former, I've ridden on a track or raced all of the bikes in my little list, and the Tuono was as fast or faster than any of them, and handled better than any of them. EDIT: one thing I don't know is how fast a Tuono/Mille is w/ a full-on SS build. If it's too fast for the C class, than none of that other stuff matters. My point was just that if a Tuono is legal, then there is no reason I can think up not to allow Mille's, TL-R's, SV1000's, Superhawks, etc.
Well, honestly no SV1k because no one asked.... But it would have to be the same rules as for the Tuono. Dave, the Mille is faster than the Tuono by quite a bit.
