Brembo 4 pad calipers are probably the best value for money mod you can make to your front setup...that said, I too have a brembo radial MC, and the difference it made was incredible (and it looks the dogs!!)..mind you that was on my 888 where the standard MC bore is about 4mm !
Magura do a nice MC too..but its gotta be brembo on a ducati hasnt it ??!!!!! I note that Alan (AJR) in Reading has some tasty deals on brembo radial MC's at the minute...dont forget theres different versions too..both in stroke, and a choice of billet or cast. I would go for a 19x18mm.
I also have the proper brembo/ducati inline brake switches here .. part number 96818500b..£28 from a dealer...£20 incl post from me
Cheers
