Looking at the mounting options available I noticed the BMW mount just screws in to the vibration damper with the same three screws as the ball mount. I made a custom one myself which utilises the same connection method and the screen lifting handle above the dash, so it can be fitted a neatly as possible on my bike and not look like a phone / tablet stuck on waiting to be stolen.

Obviously Chigee cannot go making a special mount for every bike but you could easily adapt this to other bikes.  I will upload it to one of the 3d model sites and share the Fusion 360 CAD files. 

Not used it on the bike yet as I am reprinting it in black PETG-CarbonFibre.
