Regarding the challenge... I spent LOTS of time testing bikes for Performance Bikes at bruntingthorpe. Its not a track as such. Its a massively wide 2 miles plus long ex runway, (Where we speed tested everything and did standing quarters etc) with an almost as wide return road which is all quarter mile plus straights with constant radius "joints" as bends. The bends have grass growing through the sections! Scary on a bike...
While I was there (on my own 1100WP Suzuki = 176mph through speed trap) I was playing (bored) instead of working.
You dont need something that can corner, but something hugely fast! On most racetracks a 600 is faster than an 1100 due to superior handling. Not so at bruntingthorp where my 1100 is easily faster. All HUGE straights!
The only thing that beats a big bike round there was a guy called peter taylor in a McLaren F1... And he was coming through our radar speed trap at
225mph... Looks veeery coool And you just hear the thundering noise of the air and see a silver flash. Then as it passes brake lights and swirls of dust as he tries to slow and miss the resovoire at the end...
From low speed as we both entered the long straight runway after a tight entry road, my bike destroyed the F1 up to say 120mph (few secs) and then as I watched the car in my mirrors getting smaller, it started to gain on me... About 140 and it was really catching me up! By 155 it was level but going faster than me, and by 165 it was way in front! Then I had to watch it pulling away and getting smaller!
I had nitrous on that bike next time! I felt inferior. On a big bike that just does not happen! You normally feen totally invincible...
