what doesn't translate? if you're talking about "what translates on the street" you're talking about the rider, not hte bike. whether pro or not, an ADEQUATELY ridden supersport will trounce an adequately ridden 919 in a DRAG RACE. magazine riders got about 11 flat out of a 919, and about 10.3 out of supersport 600s. these are the same riders. so the same riders on the two machines have about .7 seconds difference in the quarter.
so Secondchance may be a very good rider, or the r6 guy may suck. but there's seven tenths difference in the bikes with the SAME rider.
