Hey i just bought this bike on the weekend.
I was curious what seat this is? I am looking to put a removeable passenger seat on. All i have in the rear fender is a hole??
What passenger seat will fit? What do i need to attach it?
If i get a used stock 2 - up seat , is it a pain to swap them?
Any info would be awesome thanks..

Dont Know what seat it is but if you got a 2up factory seat it is easy swap. Remove the screw holding the rear of the seat that is on it now and pull seat back and up. Slide 2 up seat on there is a tong on the front that slides into a braket and use the same screw that you took out and install it at the rear of the 2up seat in the open hole in fender

 

Any seat you get that's for your bike will be simple to change, just one Phillip screw. The nut-back you need for the empty hole is only about $3 from HD. It's the same part that the back of your current seat is screwed into.

I'm not sure what seat is currently on your bike, but I'm sure somebody will know.

I might be interested in buying it from you if you decide to sell it.

 

Edit:
I have a seat from an '06 883Low hanging in my shop. The shape and stitch pattern match that seat.
You can get a passenger pad that attaches to the back of that factory seat (and to the rear hole in your fender) from Harley. You'll need a two-up take-off seat specifically from an '04-'06 to fit your bike. '04-'06 have a pocket in the seat pan to accommodate the ICM. It should also be a seat from a bike with the 3.3 tank. A 4.5 gallon version will work, but there'll be a gap between the gas tank and seat (because the 4.5 unit is shorter to allow for the longer 4.5 gallon tank). Some people prefer the look of the gap that's created by using the shorter 4.5 gallon seat. Aftermaket saddles have their own fitment and usually fit a broader range than factory seats. You'll also need passenger pegs and mounts, if you want to carry a passenger.

If you aren't going to keep changing seats you can just remove the e-clip from the part that the seat you now have screws into and move it to the rear hole. Then get a 2up seat that is designed for your model/year/tank size you have. In some states it is also required to have a strap or handle for your passenger along with the footpegs.

Oh, and the seat looks like a Harley-Davidson Reduced Reach® Solo Seat similar to the one here:

I have an '08 883 that I bought new and it did not have that seat on it. My stock seat is similar but the stitch pattern is different. But, I have seen that seat in the show room on a stock Super Low. I'd say it's a 2010+ seat but not sure if they're stock on all Sportsters.

 

The stock seats were changed in '07 (and again in '10) due to the new location of the ECM. It went from under the rider's butt to the rear fender. I also have a stock seat from a 2010 Super Low. It's flat on the bottom (no pocket for the ICM or ECM) becasuse the ECM was moved to the battery area in 2010. A stock seat from 2010 and up will fit on an '04-06, but you gotta do something with the ICM, like lower it in the frame or relocate it, which I know has been done.
Not my bike:

 

Great info everyone.. thanks..
