I was curious of what bikes come with master cylinders we could use. I was looking around and I remember someone saying we could use the one from the Brembo equipped R6. What other options are out there. I ask mostly because not all of us can drop the large cash to afford a shiny new Brembo MC. Is there anyplace we could look up the piston sizes for other stock MCs? I ask because I see something like this on ebay and wonder if it would work.
