Are sportbikes or cruiser style motorcycles safer?

I know motorcycles in general are not necessarily"safe", but I'm planning on getting my first bike and want to know the pro's and cons of each? Would a bike like a Kawasaki Ninja 250r be safe enough or a louder cruiser type bike like a Honda Rebel? Also, do skinny rear tires like on the 2008 Ninja 250r make a huge difference in terms of traction and such?

The traction given by a Ninja 250 tyre is more than enough to put the power down is only has 30bhp after all.A bike is only as safe as the rider. I would prefer a sports bike as if you go into a corner abit fast you can lean it more but on a cruiser parts will hit the floor.
