Can't say, as Kawasaki is a brand, not a specific model. I've exclusively owned and rode Hondas.

^^ What it looked like at the salvage yard after hitting a minivan head on at 45mph. ^^
Again, 100% the other drivers fault. They made a left turn across traffic on a green light without seeing me, placing their minivan right in my lane and leaving me no room to stop or maneuver.
What I would say is that, unless you are a very large person (either in height or weight), your first bike should be 250cc. For Kawasaki, that would be a 250 Ninja. Ride that bike for a year or two before you think of replacing it with something else. 250cc is gonna seem really fast, because they certainly can be. The nice thing is that they'll sip fuel (think 70+ MPG), they're light and maneuverable, and you're less likely to kill yourself while learning. Doing an emergency stop at 35mph on a 250cc is way easier than doing one at 70mph on a 600cc. You can full throttle a 250cc without speed wobbling yourself into a guardrail. Also, you are inevitably going to lay the bike down. You'll tip it over, or take a turn badly, or hit a curb, or something. Better to do that with a $2000 used 250cc that you can replace the mirrors and levers cheaply on, then your eventual 'dream bike' that you want to keep nice.
