Can't provide the focus you want in some regards, but the system on my Kymco S200 was bolt for bolt the same as the setup my my (similar vintage & a bit heavier) SYM HD200.
Looked like the same setup on some of the big wheel Chinese scoots I've seen, & I know the pad's pretty common as well.
I suspect most of the setups on these share common components so, with a few parts being an exception for the individual bike.
Just makes sense from a cost control setup.
