My Touring bike has an antique computer , Its main benefit is it is mounted low on the front of the right fork blade [not on the handle bars]
I mounted it just under the cantilever brake and above the top of the low rider rack .. so its out of sight.
( I only use the odometer and resettable trip function, anyhow & I can stop and look)
Some Computers are a PIA to get off their brackets , as it is ..
