97? Still have your 2 piece stock seat or was it swapped out for a later model 1 piece? It isn't hard to make a frame fitting, thinner, firmer seat off your stock front pan. A couple layers of ensolite camping pad, covered with the leather or vinyl of your choice.
Standard "chopper/bobber" solo seats are a bit small. Like the look but want comfortable, go for one designed to fit a Harley K model (side valve predecessor of the Sportster). Or an early, pre-75, Ironhead.
Very early in my bike's modifications, probably late 1999 or early 2000. Seat was good for several hundred miles a day...
2006 or 2007, same seat...
I still have that seat. It needs a couple screws and washers replaced that hold the leather to the pan, but it still works fine. May swap it back and forth with the big 2 up seat I have for it now. VN800A with Mustang fancy cover. Buying a cheap generic solo works, but durability is an issue. I had one on the Savage for a couple months and wore the cover out, the vinyl was paper thin, the padding was too soft, so the pan cut its way on through.
Whatever route you choose to go, make sure you spend the money on a decent cover. Or plan to buy an old leather jacket at the 2nd hand store and recover the seat...
