Any 600cc sportbike 1988 or newer handles plenty good and is forgiving with the right tires. Unfortunately, I haven't found a bike yet that is self governing depending on the corner and that will prevent a rider going in too hot! You could try breaking your right wrist to keep you from twisting too hard, but you would have to keep breaking it every time it heals.
Seriously, they are all good. I am a STRONG believer in NOT buying new. I would say 50-75% of the people I know have gone down within 2 years of starting (Mine was 1). The pain is compounded when you have to pop a couple grand to get it on the road again. Get a good used 600 for $2-$4K. I prefer the Suzuki or the Yamaha, but they are a little more "sport" oriented.
I am also a strong believer that it takes a lot of disipline and respect to ride a bike fast and not get in over your head. If you haven't already, take the safety course.
