Thank you all for the replies.
Rifle scabbard attached vertically to the front fork semi like you would with a horse,but not the same..I have used that on multiple motorcycles and tote gotes through the years.

I have thought that this may be the most convenient for accessing the rifle in a hurry, but do you find that it interferes with the steering in terms of the extra weight on one side and/or reduced steering lock?
