Problems of YZF600R

Since I am considering buying either of the below as my first bike in the US, I thought I should just list out their known problems.

First, the Yamaha YZF600R:

The bike I am looking at is a 2002/2003 pre-owned... To start off, I've read these:

1. A weak second gear. (I should wind on to full throttle in second and if it pops out of gear, or if the gearbox feels sloppy or clunky, it is an expensive repair proposition).

2. Exhaust Headers: It seems they are of cheaper quality and they tend to rot in colder weather.

3. Rear shocks lasts till 20-30K it seems... But I guess its not a major concern for me now.

4. Also, some standard fall backs of it are: Poor headlight, carb-icing (since its not a fuel-injection engine)


Kawasaki Ninja 250:
This is what I first thought of buying, however, time's changed my mind and I'm more inclined towards the sexier YZF...

Of course, this is a true beginner sport bike and has been lauded by pretty much every reviewer in the business... and underplayed by pretty much all the dealers :D

Anyone has any thoughts on the YZF, I'd greatly appreciate that!
