Seafoxfl, I noticed a 110 derby cover with trim ring on a Black 2016 CVO Street Glide at the dealer not long ago. It would be the slim type cover. If you will get on some of the online parts finders like:

Can probably find it.

 

This may be an old thread but it had the info I needed! The search continues!
