You are severly dilusional if you believe that 274lb's is the wet weight with a rider, with gas and a rider that would be (shocking!) about 450 or maybe a little more. I was qouting RACE WEIGHT, maybe you didnt notice that I added on a rider for the bike to make the power to weight ratio's similar. Ok, lets say Aprilla does make a 250 twin that has 113 fwhp, you really think that is gonna add 40 mph and take off seconds from their quarter time??

If you had any experience in racing, especially in drag racing, you would know that saying "o this platform with roughly the same power to weight ratio runs 9's, why can't this complelty different platform run the same??" I noticed you basically quoted the times for a busa', that thing barely dips into the 9's, just barely. So you think that a 250 twin with no suspension can hang with a full race drag bike (which is what they are, I have ridden one and those things can't handle S's at all)?

You say the European tracks have longer straights (very true, I have been to silverstone and lemans, not raced on them though), but why is it the link you gave me to "prove" how fast the kart where state that the top speed was set at Daytona and besides it only says approx 160 (very far from 180 you stated earlier in this thread).

O and sorry about the accident, I've know how much it sucks to loose a steering hub.

P.S. To your earlier comment on how 250's fly by my, of course they do, but I have rocked many a 80 cc shifter. They just dont cut it on a real track.
