Best brake fluid?

I ride a 17 rc390 and I was curious what brake fluids you guys use.

If it males any difference I ride street, mostly commuting but I really like going on backroads and would like to take it to the track sometime

I run Bel-Ray Super DOT 4. The dry boiling point isn't as high as Motul 660, but I never boiled the fluid at the track either.

Agree. Unless you're having heat problems, just about any DOT 4 fluid from a new container will probably be fine. I have a stock of Motul 660, and probably will use it in the 390 as well as my other bikes, but it is overkill, except for my Diavel's rear brake, which is very sensitive to heat.
