It depends heavily on the type of turn, there's no one answer for this question.
For example, if you're doing a U-turn, you want to look completely over your shoulder and behind you down the road. Literally turn your head as far as your neck will let it go and just lock your eyes on the traffic light a block or so away.
For normal turns the bottom line is, to really understand what to focus on, you need to know the turn really well. Even a professional AMA racer couldn't get on a track for the very first time and ride a perfect lap. You need to have a good idea of how sharp the turns are, what the grade is, etc.
This sounds wierd at first, but it's true. If you are making a sharp turn (a hairpin, perhaps) to the right and you have a cliff side on your right side, you literally want to stare straight at the cliff while you're turning. The reason for that is because, of course, you do not have x-ray vision and you cannot stare at the turn becuz...you guessed it...there's a cliff blocking your view. But, the road is there, whether or not you can see it. so, as long as you keep your head turned way to the right and you keep your eyes directed on that cliff as if you could see the road on the other side of it, you will make that turn effortlessly. It's a really wierd thing to get used to, I'm still getting used to it myself. But, that furthers my point that you really need to know the turns well. YOu couldn't possibly know how far to turn your head or that you had to stare at the cliff unless you knew that the road kept curving around that bend. Make sense?
Also, as far as focusing on just one point, don't do that. That's called target fixation. YOu took the MSF, so you understand that if you look at an object while riding, you will hit that object. If you're on that same road with the cliff, and you lock your eyes on a single piece of that cliff (maybe a shrub or a big rock), that's gonna mess you up. You want to let your eyes move along the surface of the cliff as you move, but you want to keep your head turned toward it and keep your eyes locked on that turn behind the cliff.
Essentially you want your eyes to continuously follow the road ahead of you. If you are entering a turn, your eyes should already be looking at the exit of hte turn. If you are exiting a turn, your eyes should already be focused all the way down the end of the straight-away and on the entrance point to the next turn. If you have something blocking your view thru that turn, stare at whatever it is that's in your way as if you could still see the road behind it.

Your reply went up while I was still typing. Huge +1 here. Go at your own pace and you'll never end up in a situation you can't control.
