I am going to be ordering my 4 piston calipers, to upgrade my OE BBK this week. I already have stainless lines. The only decision left is brake fluid. I have narrowed it down to ATE Blue, or Motul 600. I have used the Motul fo several years in bikes with no issues. However I usually change regulary, (after each track day). No complaints. However, I have read it attracts more water, and should be changed more often. Ate has similar boiling point, and does not attract water as much, and is half the price. Performance wise everything I have read about both is good.
Here is picture of the new calipers.

 

All comes down to the boiling point you need vs your desire to change the fluid. If you NEED that high of BP, then you will just have to change it more often.

 

+1, there is no magic fluid that gets you the benefits of both high BP and low maintanence, you have to pick one or the other unfortunately

 

I was recommended Valvoline Syn, full synthetic. I'm not a track person, this will be for daily driver, but you might want to look into it as well. It's a DOT 3 & 4 fluid.
