If it looks like this one, then yes, with some mods.
This one is made by Add ON and Markland made one just like it. They sell these as fitting both the 1100 and 1200's depending on the brackets that ship with it. I have this on my 82 1100 Interstate but it came with support bars to also install it on a 1200 or even a standard 1100 without saddlebags. What I didn't use to install it on my 1100, I saved.
