it just jams onto the metal rod that you push down with your foot to use tha rear stand of the motorcycle. I certainly do not suggest to ride with these light shoes I am wearing in the picture, I just sometimes have to rearrange the bike in the evening (barefoot or with these shoes), and the thin metal rod is very uncomfortable then.
If you want, you can drill and tap a hole in the end of the rod and secure it with a M4/M5 screw, the hole is prepared for that. But I did not yet notice it coming loose in any way.
The author marked this model as their own original creation.
