My TB and CB never had any, I don't particularly like them. I cover the knee part of the tank along its curvature with a tough clear film. Initially it shows the remains of the glue but it disappears within a couple of weeks, especially parking in the sun, leaving behind a completely invisible protective film.
I use ScuffProof made by SportsPro Racing an Auckland company but 3M have something similar and it is also a Honda accessory part.
It protects the paint surface, Honda has softer paint and necessary and my TB tank is like new.
If you wanted pads for grip then that is something else again.
