master cylinder

Hi All, New member here. I have been searching for a master cylinder rebuild kit for the Magura clutch on my 2013 KTM Duke 690, but I can't find any kits that confirm compatibility. Feels like I'm missing something obvious! Does anyone with experience doing the rebuild have a recommended kit...

I find the brakes a bit spongy on the SDGT. I'm changing pads to the sintered Galfers and I'll see how that goes (or stops). But I'd like more brake feel and pressure. Wondering who's tried the Brembo Master Cylinder upgrade to the 19x18 and what your experience is? Its almost $600 USD so...
