They may not be needed every day, but there are occasions when the kickstand pads come in handy. They usually do a great job keeping the bikes from sinking in hot asphalt or, (in my case), damp New England clay.
After their use, however, they usually aren't clean enough to toss back into the saddlebags. I used ziplock bags in the past to isolate them, and it works, but I found another location that is easier.......for me, (ymmv, of course).
On the underside of the passenger floorboard are two screws. I removed one of them, inserted a u-shaped bent metal bracket, (after adding two holes in-line and a separate hole), and re installed the original screw. I added bolts, lockwashers and nuts to the bracket holes. I used material that was in the garage, not exactly showroom items.
I drilled two mating holes in the plastic kickstand pad it is held in place with wingnuts. If I used slots instead, I could leave the wingnuts attached after loosening them.
I check them for tightness occasionally and so far, no problems. As long as I remember to re-attach the pad before driving away without it, things work fine.
