Looking at a few motorcycles, Ninja Kawasaki ZX -10R and the ZX -6R. I?

Added (1). I'm 5'9 and I walk around at 135/140lbs.

Added (2). I'm open to Honda and i have a $20,000 budget.

The ZX10 is to heavy for a first bike.
Sportbikes for a first bike? - I gave up explaining the reasons why it's a bad idea.
Research that part of the question.
