FZ6 for first full licence bike.

[celticbiker]

i often go power-ranger baiting on my 650 versys between brecon and llandovery. all sorts of bikes ranging from RC8s, blades, R1s, MVs etc ridden by riders who cant ride them very well. bit childish for a 57 year old but fun!!

I used to do that on my tdm900,  great fun to watch them missing apexes trying to keep up.
As someone has already said, learn to ride first, the speed will come with experience.
As for a bike, I recon you couldn't do better than a fox eye six or a fazer 8.
