SuperHawk Forum - Attempt at DIY Seat Modifications

So my seat needed recovering. Picked up some vinyl at Joann Fabric and decided to give foam modification a shot. It's a worn out stock seat, so not much to loose. I followed this site:
DIYMotorcycleSeat.com - Home Page

Picked up some rebond foam and polyurethane foam for about $35 total on ebay. If you live in a populated area, you can probably go to a carpet store and get some rebond for pretty cheap. It seems silly, but this is what a lot of people use for a firm foam base layer. I used a flap sand wheel on an angle grinder. I recommend getting a high grit, or a used one if you can. I used like a 60 grit, and it would dig right into the seat. Oops.
On to the modifications.
I dished out the area you sit in and glued in some rebond. Two layers, 1/2" each, with some butt divets cut out and the softer foam added here.

Then I covered it all in the softer foam, and built up the nose a little with the softer foam.

After this, I took a worn flap sander wheel on an angle grinder and attempted to smooth this all out. And then covered it with the new vinyl.

It didn't turn out perfect, little lumpy looking in areas. But it's much more comfortable. Maybe not as good as a Corbin or Sargeant, but better than stock I think.

For those that want to attempt to do this. I recommend getting a large piece of the polyurethane foam about 1/4" thick to cover the whole thing. I think this would help make it look better in the end. I used 12x12" pieces, and that's why I had so many patches. Maybe in the winter I will redo it all.
