Here’s the one I made many years ago for my first 748 back in action again when I had the forks and shock serviced. Just slip it under and push the lever. There is a thread that goes down on the lever to hold it in position.
Quick and easy to use there's a recess under the bottom clamp that the rubber grommet fits into stopping it from slipping. Fairly easy to make to. The bike live's on the centre stand just lift it with the paddock and drop on.
