H100s seat help

[Gruttz]

Hey all,
I am helping a friend get an old 1985 H100s up and running.

The seat is in a real bad way, the cover definitely needs replaced.
The only problem is that the seat pan is really badly corroded, so there is no way to attach the cover.

We have been looking to buy a seat, but cannot find a one anywhere.

Does anybody know of any alternative seats that would fit this bike?
Or any other advice to get this sorted is much appreciated.

Thanks.

That model looks very similar to the Brazil CG125's.. Could a seat from that maybe fit?

I've seen people fibreglass an old seat pan before today.

Fibre glass and then these things which you poprivet around bthe seat base edge. They work , but watch your fingers: https://www.ebay.co.uk/itm/CLASSIC-CAR-UPHOLSTERY-AID-FORD-AUSTIN-MORRIS-VW-TRIUMPH-JAG-BMW/174337203783?hash=item28974e9e47:g:nKUAAOxyaTxRJ44I

Incidentally, if you decide to use fibreglass, invest in some bias weave cloth and epoxy resin instead of that nasty chopped strand and polyester resin shite they use for patching up cars. It goes on neater and finishes up stronger.

Sorry for the late response, and a huge thanks for all the great advice.

This is the images of the seat pan.

I think I will try the fibreglass route.
Thanks for the fixing links, they are really useful to know (That was going to be my next question).

Thanks

It would be tempting to properly repair that, it's not too far gone, I was imagining much worse.

A decent steel fabricator would be able to cut off the rotten stuff then weld you new stuff in. They do that kind of shit on rotten car sills all the time. It looks like there is solid metal round the whole "flat" part of the seatpan, and in fact, most of the rim. If it were me, I'd throw the whole thing in a big tub of white vinegar/electrolysis bath and get the rust gone then see what it looks like. Might just need patching at the two sides.

Another alternative, depending on how authentic you want it, would be to buy one of the plethora of "cafe racer" seats off ebay designed for people to fuck up perfectly good CG125s with. You'd just need four rubber door stops and to fabricate two 90 degree brackets.
