That is a production Hope RXCL rotor. I can’t see that they’d do a custom one for that bike if they’re trying to keep costs down. It is about time they started producing a 140mm version though.
The braking surface is always deeper than the pad with Hope.
Assuming the pot is aligned to the end bung.
Seems to be using half the braking surface.
Bigger rotor?
Edit. Could be lens distortion.
