ADDING foam to a stock seat...

[kmx125r]

Hi All,

I often read about guys who want to lower their KDX by way of shaving their seat foam. I on the other hand would love to add about 2" to the seat of my KDX250SR. The contours of the stock seat are especially "ski jump" style. (check out the pic on page 10 of JustKDX Reader's Rides) I'd love to have a seat like a stock '95-02 KDX200!

I'm certain that here in Manila I'm going to have to source some foam from a foam vendor, not a bike shop. Are there any special types of foam with any particular characteristics I should ask/look for?

How would you suggest attaching the additional foam to the existing foam? Glue? Do they make a foam glue?

I will get a custom seat cover made here easily by a local upholstery shop, but I'll need to fabricate the seat first.

Any advise would be appreciated.

You might be able to buy taller foam for your seat. If you add too much the seat cover might not fit properly though. What year is your KDX?
My '93 had a double seat with a custom cover. I didn't like it and eventually went back to the stock. The extra foam was just glued to the top of the other foam with silicon caulking I think.

You can buy taller foam or you could probably add some "spacer". You will want to add foam underneath the current seat foam so the top surface keeps the nice shape to it. You will then need to trim some here and there. You will proabably be looking at a custom seat cover once you do this.

Since noone on earth makes tall foam for the KDX 250 I've been considering buying KX 500 tall seat foam and seat cover and trying to custom fit it to mine by shaving where I need to. I'm hoping to get more weight over the front end by reshaping the seat so you're not stuck down in the valley so you can slide forward with ease. Let me know if you find something that works.

Excuse the crudeness of this solution, but I added 'great stuff' foam-in-a-can to the seat base in strategic areas, let it harden completely, trimmed and shaped, then reused the original foam.
Then re-contored the seat foam to be flatter front-rear, and rounder side-side like a more modern bike. I glued the trimmed foam to the areas now missing foam on the sides where the seat 'canyon' was. Its not a solution for the impatient, but did get me the results I was after. It does resemble and perform like a later-model seat now. This was all done after taking the pic for readers rides so don't look there to see it.
if it helps at all;
