will seat model # 51530-07 fit on my 2013 883 superlow?

 

Pretty hard to tell without more details on the seat, but unfortunately it looks like it's obsolete so more info is hard to come by. According to this listing (and others), which could be wrong, it should fit 2007 and later with 4.5 gallon tanks: https://picclick.com/Harley-Davidson...465999828.html.

Is there a way you can try the seat to see if it fits before you buy it?

 

It should fit if you have a 4.5 gallon tank.
