The top speed of any bike is directly proportional top how high you drop it from.
That being said: do some research, I think the vee is limited in 6th (and maybe fifth too). Top speed might be easier achieved in th or 5th.
OH: do all the research; it seems that these bikes become slightly unstable above 200 km/h. (I don't know, my wee only reaches 180, but I've had an 06 up to 200 with no problems)
I know I felt a lot more comfortable/confident/in control on my 1985 gsx1150 at 260 km/h than I do on the wee at 180 (since the vee is basically the same bike, I can't see it being any more stable at that high a speed)
