After adding bar risers to my xsr700 for comfort the standard Speedo mount did not work. I also use a quad lock phone mount where the Speedo used to sit so needed a solution to mount the Speedo. Not liking the price of anything I saw online I designed this, and after many test prints this is the version that works best for me.
It mounts to the original bar mounts, hides the wiring from the back, lifts and offsets the Speedo for better visibility too.
I printed at 50% infill for the mount with supports
15% for either back cover with supports.

NOTE: this probably won’t work without bar risers. My bike is a 2017 and I haven’t tested it on later models to see if anything has changed.
