Correct. The 3/4" was ment to be 7/8". Anyhow, It's "OD"
Thanks
what size bars do you have doubledog, 1'' or 7/8"?
from what I can make out Triumph have two OEM bar mirrors available
A9638020 for Thruxton 1" bars
A9638056 for T100 and Bonnie 1" bars
dont know what the difference between the two are as both for 1" bars.
I am looking at fitting bar end mirrors to mine as well and this is as far as my research has taken me
1" bars have a 20mm inside diameter
