I ride an 06 1000RR. I am only -1 in the front. I can pull 3rd gear, 130+mph power wheelies, hold it there at or around 140mph.
What are you trying to acomplish by going -1 +anything on a litre bike? The fkrs have plenty o power just liek they are and -1 is sick on the street. Anything else is just overkill.
Furtermore, if I am not mistaken, you start going + a bunch in the rear and you shorten the wheel base of the bike.

I run -1 on the front and stock rear on an '08 GSXR-1000. It gives good drive out of the turns and is manageable, but I'm a pretty big guy. -1 is not as dramatic of a change as you might expect. You can always start with -1 on the front and then change the rear at your leisure, it's so darned easy.
BTW, I did not go to a 520 when I made the change. On a liter bike, I just don't think it's warranted unless I was a top runner in the CMRA novice classes.

I have ran -1/+2 , -1/+1, and -1/stock on my R1 (520 Chain). I think the best is -1/+1 if you have stock wheels. I recently went to a much lighter front wheel so I had to go with a stock tooth count on the rear sprocket.
It can become a little wheelie prone, but it is very manageable. The 520 chains last a long time on my bike. I clean and lube them often, though.
You can pick up rear sprockets with aluminum carriers and steel teeth if you are worried about it too much. The Afam sprockets have always worked well for me. Hard to go too wrong on the chain if you stick with the top manufacturers DID, RK, EK, Regina, Renthal. They make a 520 with more tinsel strength for liter bikes.
