My fat carcass has compressed the seat foam of my trusty old '84 K-100RS. I use the taller European model seat, not the US spec low rider seat. I cannot find foam of the same density as the original nor can the local upholstery shop. Does anyone know of a source of appropriate seat foam I can order a block from? Thanks.

May be you will find what you need there:

The German word for foam is "Schaumstoff".

It a German site and the English translation doesn't work for the foam, plus the pricing is all in Euro's. Humpf.

Do any US members know of a source of seat foam?
