I have had the GPx up to around 11600-11700 in top gear*
getting a tow from Dan down the front straight at PI (track day of course)
the speedo on the GPx said about 255
(not game to take the eyes off the track for too long)
Dan reckoned his speedo said 260ish
so
I reckon somewhere around there
which btw is pretty good
I have the TW mag with the original road test of the GPx when new
they got it to just over 250
*for the track day, I swapped the rear sprocket for one with one tooth less than normal
I am happy with that, coz its pretty good for a 17yo bike
with skinny tyres

and 250 is fast enuff on 2 wheels for an ol'bloke like me
