I have the Kuryakyn Ultra as well. Work Great. Nothing like pulling into the hotel after a long day of riding, pop open the hard cases, pull out the luggage and walk straight into the lobby to your room., I'm still looking forward to a hard top case that is easily removable. There is a forum member who was working on this solution. His drawings and renderings look promising. I especially like that he was working a slide for the base to move it forward for one up riding. I will see how his mock up turns out.
