Aren't those the people that copied CRG?
A great all metal master cylinder comes off of a Kawi ZX6D. It was the 2nd generation after the original ninja 600. You can go to a motorcycle salvage yard and look for bikes with all metal master cylinders, then double check there are 2 calipers with 4 pistons each. And/or look at the bottom of the master cylinder for either 16 or 5|8 meaning is 5/8" bore size and will work with the brembo calipers.
I had one of those on my 900ss and really liked it. And then it went onto Zina's 900ss:
