Regardless, the new bikes have never substantially increased the lap times. So, unless you're a top flight expert that need the correct bike for contingency, get the simplest one.
For reference...
At Blackhawk in 1993 just about everyone was riding Honda CBR600F2's. Mine made 94HP and I could do lap times in the 1:16 range with the fastest 600's doing 15's.
In 2001 on my 104HP GSXR600 that has ram air (that doesn't get factored into the HP number), weighed in at 30 pounds less, had four piston calipers with floating discs, larger rear wheel, FI, and cartridge forks....
I did a 1:13 something, fastest 600's doing 13 somethings. All that technology, in addition to the tires, which do feel better, I managed to go two seconds faster in almost ten years.
The bike won't make anyone much faster. The rider understanding the set up and taking advantage of that will.
