No reason those calipers and rotors shouldn't work together if they're as advertised.
Hundreds of people have done this brake upgrade.
OK, I called the mechanic back to get 100% clear on what he was seeing. When he reviewed the parts again on the phone with me, he changed his position and said that they would actually fit. However, the rotors are right at the minimum thickness, and the calipers are in rough shape - so his recommendation was to stick with the stock setup - it's lower spec but in better condition. My plan is to let him flush and reassemble the stock setup, and I'll tidy up the calipers & pistons and pick up some new pads, and maybe revisit the swap after the riding season is over.
Thanks again to all for the info.
