Just for curiosity I made a search, is difficult and no first brands (only Brembo, but no like this), too much chinese disks and enduro oriented.
I think is logical, the braking conditions changes compared from OEM , it has less braking surface then has different braking conditions. Probably is my apreciation, but I see the disk with dark brown color, overheated.
Needless to say I don't like it as brakes, but are really cool!...
