Looks good. I have made a few for various projects in the past. One thing you can do is use two pieces of tube that telescopes in itself on the vertical offset portion (just to the right of the screwdriver in the upper picture) and use a jack screw through the center axis of the tubes with a nut plate to adjust the height. (can even scavenge the parts from a large C-Clamp if needed) This allows adjustment for other items that may have a bit different center of gravity as well as adjustment as you add or take away from the vehicle that you are working on.
We made one when we fabricated the chassis to this unmanned vehicle. Primary materials of the chassis were AL5456 and Ti-6-4

Any day on a motorcycle like this that ends just needing parts and labor is a good day.
