Brat or other seat options for a R100S

Thinking about trying a different seat style for my 1978 R100S (and maybe ditching the fairing). Anybody know of any companies producing options? Would rather not try to fabricate one.

You should make it a Cafe Racer, no one ever does that.

Gotta fix it right somehow

or he could make a GS/PD clone

or just put it back to stock with only NOS pieces that were dipped in the blood of Teutonic babies prior to being placed on a shelf in 1981

I've been looking for something bolt on too. Unfortunately I haven't found anything suitable. It seems the formula most people use is to fabricate a new rear subframe and them mount a generic seat.

I've seen a whole subframe and brat seat set up on eBay a few times for around 300$US.

I've seen the eBay one too, but couldn't seem to find it. No experience with either.

When I asked the ADV community about the ebay set, I was told it wasn't strong enough and to avoid it.

Send Vonzeti an email, they do a whole range of rear sub frames, I'm lucky as they are only 30 miles from me, so I went to their workshop prior to buying and was very impressed with their fabrications. I've ordered a new rear sub grand and seat, which is due next week.

They make all the frames for Kevills Speed Shop, so must be doing something right!

HI - I've looked at their site. Unfortunately all their pictures make it hard to see the actual quality of the item. Choosing a **** bike as their marketing shot also does them no favours!!!

Does anyone have any pictures of it mounted to their bike?

I made this one for my r80. keeps the stock subframe and doesnt modify it. I made a stout brace that bolts to the front to keep the pan level.

Stumbled my way onto Down & Out's FB page via a photo I saw. Looks like they are producing some subframes that might solve your problems. I'd imagine they aren't cheap though. With I had a better link, but this is the best I could dig up:

I'm mid-stream on building a seat. I picked up a somewhat busted subframe for cheap as I didn't want to modify the relatively clean one that came with the bike. A few cuts and it was ready for welding. Some fiberglass and it was ready for foam. I'm haven't had much time to finish the foam - it's crudely shaped for now - but when it's ready, I'll have it upholstered by someone with more skills than myself.

The temporary cover is made from an exotic polymer blend (aka trashbag).
