use either MOTUL RACING 600 or BREMBO LCF600 fluids, they are the best in that they offer the highest boiling points, very low compressability and are extremely good at not sucking up water. You have a ducati with BREMBO componants so you must use a non silicone based fluid as BREMBO uses natural rubber seals. This specifically means DOT 4 only DO NOT USE DOT 5 FLUID!!!!!! This *will* ruin your brake and clutch system eventually as the seals will swell then degrade.
