Can the same backrest from a 2010-11 street glide be used with a 2011 sundowner? I'm talking the non-adjustable backrest (which is actually adjustable but not via wire on the fly). Been getting opposing answers on this.

 

yes, same setup since 2008.

 

If you're talking about the HD quick-release Short and Standard height uprights, I think it would be more practical to go with a Standard height upright, given the additional height of the Sundowner.

 

Cool. Yeah I know the seat will fit, but I had folks telling me there was a proprietary back rest for the sundowner. I was at a dealer and wanted to ask Saturday, but the place was mobbed and I couldn't get any time with anyone to ask. I did look at a sundowner seat while there and it did NOT have hole going all the way through to accept the backrest...was that because it was a demo seat only? I don't know, but added to my question instead of answering it.

So you have all the info; the backrest I have is 51631-09a

Just trying to be sure I can use it with the sundowner for my 2011 road king

Thanks to everyone

 

Based upon your part number, I misunderstood your question, Night Train. When you used the term "backrest" by itself, I thought you meant the passenger backrest.

The data on the Sundowner says that it accepts a rider backrest, but as you say, it doesn't appear that the seat is slotted. So how would the rider backrest attach? It's a mystery to ME.

Maybe someone who knows better will chime in.

 

Thanks so we are back at square one I guess thank you

 

I have a 2010 RK with a Sundowner seat and a StreetGlide seat the back rest fit's them both along with the stock seat.

 

The Sundowner seat on my '11 SG has the slot for the riders backrest.
I don't have/use a riders backrest, but can't see why it wouldn't fit both seats.

 

I have a 2010 street glide with the matching rider and passenger backrests. I put the rider backrest on my sundowner and it works just fine. The sundowner does have a slot for the backrest, the seat you saw must have been a demo. You just need the backrest bracket to mount below the seat. Gallery pic below.
