Thanks matthews677 - I think there is a training school in Chippenham but I need to find more details of this one. I've just checked out the ZX6R - very nice! I was I bit worried that I'd have to be on a 125 for a while - being 14 1/2 stone, I think I'd look a bit silly! I did like the look of a older GPZ500s late 80s/early 90's - I quite like the retro look and the reviews I've read about them suggest they're quite forgiving for beginners.

Cheers
