Bicarburatore / Sport seat

Post by Vintage Veloce » Sun Oct 07, 2018 1:47 am

Does anyone have photos of the metal framework of one of these?

Did the original seat have springs? How was the frame constructed?

My seat is made of steel sheet, no springs of any type. It is rather hard! I've always assumed it was not original.
Here is a picture of the underside, looking back toward the fender.

no springs in that seat, they are fairly grim for anything other than short trips, earlier sprung seats are far superior but shaped differently, choice depends on how original you want the bike to be ?

Hugomez,
Wow, that is lots of stuff, and confusing!
Italian Seats, Argentinian seats, Long Seats, Short Seats, Sheet metal seats, Seats with springs!

And now I see some of the seats hang off the back of the fender. Maybe that is from using the wrong seat for the big tank?
Can anyone summarize these differences?
Thank you!
Carl

Hi Carl,

Indeed the subject is confusing, with a lot of information. I can tell you about my own experience with my Bicarburatore "Long distance" that has the big fuel tank (18 liters) versus the standard fuel tank (13 liters). From factory the "Long distance" came with those seats that are thinner and doesn't have springs. Not very comfortable as you now.

In my case is not very clear if is original or not, because if I compare with the original once that appear in the page 70 of the Moto Rumi Book (Ricardo Crippa), the seats there are longer, but the truth is that I really like shorter as I have it in my Bicarburatore.

I don't think I will be able to know ever if my seat is original or not, and maybe you will also not be able to know, but what is sure, is that from factory some Bicarburatore were coming with those seats.

I do not remember if your white Bicarburatore had also the fuel tank for the "Long distance". In case you have it, I think you can't mount the seat with springs, because there is not space for it.

Please if somebody think that my information is not correct, or there is some valuable extra information to add for Carl, please feel free to say it.

Mine after a professional upholstery looks very nice. No plan to change it even if is not very comfortable.

Hugomez,
I also have the larger, more curvaceous, 18 liter tank.
That was how I had it for the motogiro, with lots of gear attached. I had redone the seat to add padding.

When I bought the bike it had a beautiful leather and suede seat that had very little padding:

I want to do the seat again, and I'd love to have a more comfortable seat with springs. DO we know, did any of the Italian bikes come with seats with springs?

I just found this picture of a bike that was sold in Italy.
More pictures here:

Perhaps all of the seats with a wide spot in the center like this have springs?

Hi Carl,

I think the only once that has the straight seats (with no springs) are the Bicarburatore that has the big fuel tank as we both have. The rest of the Bicarburatore I would say were leaving the factory with curve seats (with springs).

The last photo you posted don't show the fuel tank. Is there any other photo where we can see it?

As mentioned before, if something think different and can add some information, please feel free to say it :D

I just purchase a seat on eBay, and it looks like I will be able to modify the frame to get it to fit. Should be an interesting project!
In case others are interested, this was the seat I bought:

Interesting, thanks Carl for sharing.

Please let us know the final result once you have it modified and added to your Bicarburatore.

Greets,

Just got these pictures from Italy of 3 different seats. Supposedly these are all Rumi seats, but I don not know if they are all "original".
