Default PM Calipers

According to PM's website they manufacture a 6 piston caliper for the front. 1 for a stock size rotor and 1 for a 13" rotor. One of them states it requires a master cylinder change to work.

I have PM's hand controls and master cylinder installed on my bike.

I sent several emails to PM and all I received were generic responses like they weren't interested in providing any information.

Does anyone know if the 6 piston caliper with the 13" rotor will work with my current setup without any changes?

I just called my PM rep for you. What is boils down to is 9/16" master cylinders vs. 11/16" master cylinders. You mentioned already having PM controls, what size master cylinder do you have? To use the 6 piston caliper with the 13" rotor you need the 11/16" master cylinder, if you already have that size you are good to go, if not you will need to buy that one and sell your 9/16" master cylinder. I hope this helps...

Thanks for that. That really sucks though. I emailed them and asked them what I needed they provided the part number for the 9/16. They are installed but I have never ridden it since installation.

Unless you are running dual brakes on the front, you don't need a 11/16" master cylinder.
