Here's mine, Drag Specialties Predator seat. Very comfy & gives solid support, for me & passenger. Not as chunky as the Sundowner & matches the bike pretty well.
I'm very satisfied with it!

 

Where did you get your backrest? I recently uupgrade from a sportster to a slim and have been looking for a backrest that doesn't require the relocating of the tail lights but cannot find any so far.

 

It's a Bowmans Sissy bar. Many Slim owners seem to have 'em. They are pretty easy to install, are great quality, and seem to be a pretty good company too. Hand made in the USA!

 

 

Hi Chmelion, it is a unique setup!
I am very interested to know your solution about the sissy bar; I am also looking for something that does not require side plates and mostly relocation kits

 

Kuryakyn plug and play. I got mine used but they sell it new also. Fits directly over the 2 seat bolt holes, than the stock seat and pilon and bolts hold everything in place. There is a rubber pad on the bottom of it.

 

The deluxe seat took slight modification. I used the factory bracket that normally goes up from inside the fender. Drilled a hole on center to attach it to the fender with the single hole. Lastly I put a piece of rubber under it to avoid scratching the paint. I have about 12 looks to flip through in about 10 minutes

 

Wow. Mice job man.
Thank you for the info! Very helpful
