Yamaha GT80 76' double seat foam replacement #1
Hi everyone.

First time poster, joined the group to learn and hopefully contribute to help others at some point. Love my Yamaha Vinduros!

I've come into possession of a fairly neat 1976 Yamaha GT80, Australian released model, with the double seat. I'm looking to 'tidy' it up and only restore the parts needing a lot of love. Only 3700km on the dial, and the numbers are lining up pretty good - maybe genuine travel.

Currently making the bike road worthy again for Australian roads (indicators, mirrors, etc).

All seems pretty good for its age and original, however the seat cover at some stage has been replaced.

I have a replacement replica cover for the double seat, but am beating my head against a wall trying to locate a foam to suit.

Plenty of single seat foams out there, but not the double.

Would anyone know of another model which shared the same double seat, which might help with the hunt for a replica foam?

The double seat is approximately 600mm long (23.62 inches).

Appreciate any assistance.
Rhys

Welcome! from the UK. Jeez, we threw away the cricket yesterday! :Ugh

Anyway, a good start for finding out what other models used that seat would be to find a parts manual for your model and search under the number for the seat and see what comes up. Also search the European fleabay sites (.de, .fr, .it etc). Ordinarily I'd suggest CMSNL or Partzilla, but they don't carry parts lists for the early Aussie models.

What you might think about doing is contacting KDI (see link on the right) about the type of foam that they use on their repro stuff - they might even sell you some. Once you have some suitable foam, you could see if there is an upholsterer in your area who can trim the new foam to match the shape of the seat, using the old foam as a guide. Thinking about it, I guess you could find an upholsterer before ordering any foam.

Good luck.

Maybe next time eh?

Thanks for the tip mate, that's a great starting place finding the part number and (fingers crossed) sourcing one used on other models.

Found a local upholster who was telling me to source a repo, otherwise I would be spending a tad on forming up one from scratch.

Let you know how I go.

I have found a parts manual and obtained the part number for the double seat assembly and cover.

Assembly:
376-24730-00

Cover:
376-24731-00

I've tried Googling these with no love... looks like Yamaha used similar part numbers, but changed the first 3 digits based on the bike/model.

Anything else I could do?

Would anyone be able to assist?

The Yamaha dealer Network in Australia and New Zealand run a Redundant Parts List .
This is where Dealers list their NOS stock that they'd like to shift . Great for finding
some NLA parts . A good Yamaha Dealership should be able to check whether
either of those parts are lurking on some Dealers shelves .

Recently I mentioned that the US dealer network must have something similar. I found 1988-90 DT50 headlight bulbs that way a few years ago. The closest Yamaha dealer to me has a horrible parts department but the one across town will search other dealer inventories and tell you who in the US has one.

They also have a brake shoe cross reference sheet of some kind where they can get you Yamaha shoes for older models where the parts list says the shoes are NLA.
