Sorry, 3th3r. I totally din't answer your question.
No, I have no idea where to get the hydraulic clutch setup. But it will entail a new clutch cover $$$.
The new Monster that I test rode had a cable clutch, probably to save weight and cost.Currently owning a Monster with a hydraulic clutch and a GSXR with a cable clutch, and having worked on both, I can say that neither system is inherently more complicated than the other, just a different application of technologies that achieve the same result, and there advantages and disadvantages to both.
