YZ 125 H seat foam.

I normally toss these things out when I recover a seat but this original one is in pretty good knick. It doesn't seem to be coming apart at all. It is softer than the replacement foam so if you have a tender posterior then it may be what you're looking for. Pretty sure the G model has the same seat.
Thirty bucks plus postage will get it to your mail box.

I have a rotting, mould infested lump of timber around the back of the shed that i occasionally use to scrape mangey wombat carcasses off my lada niva when i returm from koala hunting. Interested in a swap arrangement??
