So today these my CM185 exhaust brackets turned up!
I test fitted them and they are going to work great, they even have enough of a curve on them to clear the swing arm. After a test fit this is what i have.
I just need to fixed the top of them down, i have considered welding in some captive nuts onto the frame, but i would like to be able to create a bolt on kit so i am investigating using some handlebar mirror mounts.
Ive ordered a pair and they are designed for 7/8" handle bar, which luckly is the same diameter as the frame! I will report back once ive tried fitting them.
