Brembo is the way to go.
For example the rotor is really floating and not just marketing talk = good on the race track when heat is building up. The color of the "buttons" on my stock rotors had changed to blue after a few heavy track sessions..
And the Monoblocks seem to be one of the best calipers out there. Yes, some argue that ISR is the "best of the best" but that's another story.
I have the RCS19 brake master cylinder installed but it looks like I'm going to have to change it = the lever hits the inside fairing really bad when turning left. I was told this German company called
ABM have a master cylinder that could be something near in class with the RCS19. I have to check it out.
It was dumb of me not checking the measurements of the RCS19 because I already had problems with the Pazzo levers before. I tested my (revised edition) Pazzo's on 4 different busas and my bike was the only one that had clearence issues. So the fitting of the inside fairing doesn't seem to be 100% when compared between one another..
