yes a 650... it goes crazy fast if you open the throttle full on...
but ok, it's a friendly bike, and should be a good way to start if you have some experience, or some talent...
the 4 cylinders are also sweet and slow if you don't fully open the throttle... but it's hard not to.... it's kind of an addictive thing... and dangerous...
I believe that buying a big bike is skipping a few steps on the learnig curve... some people get over it and become good riders, others don't...
My advice is: get a small bike, you can always change it after a year or 2
