How difficult was this to do? I'm 6'0" and just a smidgen more height would be perfect.
All you need is a piece of 1" open cell foam, which is basically the inexpensive stuff you get for a camping mattress, ans a good staple gun with the shortest staples you can find.
Remove your seat from the bike to make life easier.
Take the cover off by removing the current staples.
Cut the foam to the desired shape. I just did the front part of the seat, which also let me only remove the front portion of the vinyl cover, but you could do the whole seat.
Place the foam on the existing closed cell foam and stretch the cover back over it. It is good to have a helper for this part.
Staple the cover back in place. The plastic that you are nailing to is relatively thin, thus the small staples are a must.
That is it. Happy butt and a little more height.
