I work in a bike shop and am amazed at the number of people coming in for gear having just passed their direct access test, then gone and bought themselves a shiny new GSXR1000 or Fireblade etc.
Often these people have never ridden bikes ever in their lives, but because their mate who's been riding for a few years has one they have to have one too
I'm all for freedom of choice but when does that stop and stupidity begin? The phrase learn to walk before you run springs to mind. Start with something less powerful and more forgiving and build up your roadcraft and experience. After all, experience can only be learned, not taught.
I dont think I'd ever recommend anyone get bigger than a 600cc to start with, and even then I'd say go for an older model, like a CBR600F or early ZX6R's. quick enough to have fun with, but no so bonkers as a 750/1000 of a newer version.
