Ok now I'm even more confused. The bar end mirrors came and they don't fit. Here's a pic of what it looks like

Behind that rubber is just a small hole pretty much the same diameter as the hole in the rubber. The expanded piece is apprently removable with an angle grinder whish I really don't want to do

Hi, I'm super confused about my bars on my duke. I have seen videos of people fitting 7/8 bar end mirrors fine on dukes but I've had a look at mine and it seems they are not hollow and just have a thread inside, I have some bar end mirrors coming tomorrow and I don't even know if they will fit as they aren't hollow. Any advice?
