sorry man but no way in hell a 70-80 horsepower ape will show a r6 with a good rider on it its tail.
at least 40 hp difference even if you tune the ape make a big difference .you know even on a twisty circuit there are straights connecting the corners
the problem with the aprilia is that in slow turns you really need to use the clutch to keep the revs up and quite frankly i'm not good enough for such techniques.i'm happy when i hit a breaking point more or less at the right time and i get my knee down
sad thing i probably won't get to ride 2 strokes when i'll be better, i hardly ever see one these days.125s at best
edit : i know there is the possibility on a really twisty circuit (we're talking racing right? on the street anything thats capable of 130kmh is enough,handling is king there) that a pro rider can take advantage of having no engine brake and whatever.but for me the 2 stroke although it is more fun is much much harder to be fast on, much more gear changes and the lack of engine braking means i run wide in every corner.maybe i'm not good enough on the rear brake and can't coordinate all things at the same time but i can't imagine normal track riders to be faster on a 250 than on a 600
