I took the seat off of the Goldwing and did some gel and foam mods to it this weekend. Here’s a web page I made showing in detail how to do this mod. I’m sure the general process would be applicable to many other bike seats as well:

Here’s an image:

Tools required:

Narrow bladed screw driver
Wrenches to remove the seat
4 inch sander and disk
Very sharp knife or razor knife
Spray adhesive
Staple gun and small staples (1/8th inch)

Materials:
Memory foam – I used 1/2 inch thick foam
gel pad – I used 3/8ths inch thick gel pads

I cut a bit deep so I used three pieces of foam and two gel pads in my seat. Only things I might have done differently is cut a bit less deeply when removing the old seat foam. This would have saved a layer of foam and one gel pad. I also might have taken the top layer of new memory foam right out near the edge of the seat. All in all, though, I’m very happy with the change to my seat. It feels much nicer than my stock seat did and I’m glad that I did it.

Ride safe,
Zippo and jax
