Question about Quad Lock Motorcycle Mount Pro

Has different ones, you'd have to google it. I have one on my 23 XSR900

So the question still hasn't been answered correctly. The bracket is available for the following handlebar diameters: 22 mm, 25 mm, 28 mm and 32 mm and for 38 mm, 44 mm and 51 mm. So there are two different mounts. Why is this (most important) parameter nowhere to be found?

There are 4 different adapters.
Should fit all standard motorbike handlebars.

For which exactly, e.g. 24mm or 35mm

For various diameters, as it is adaptable.
