750 S / SF seat length???

[Smartv11]

I want a hump seat for my early SF (1970/1) to replace the dual seat, but I'm confused by the two versions that seem to have been offered.

There appears to be two versions, a shorter hump seat (where the seat rail hoop can be seen) and a version which covers the seat rail hoop, this version is approx 68cm and would be the same as my dual seat. I first thought this may be a difference between an S and SF, but I don't think this is the case?

I would like the shorter version, if any one has a spare?? please!

(I'm not excluding the idea that all seats are the same and seat rail is different - I don't know?)

???no replies?

Could I ask how long a 750 S seat is?

Thanks

I'll have a look when I go to my storage later in the week.  There is a visual difference between the S, SF and early triple single seats in length, but also in width I think.
I know a triple seat does not fit an S, and vice a versa - well, not without work on the rear seat mounting bar on my examples.

The hump seat on my 1971 SF, which I think is original, is about 27 inches long (68-69 cm). It extends a couple cm beyond the rear frame loop.

my 71SF shows the loop.

Love the Breganzie 71 SF - I grew up with it.

Correction here, both my GT and SF  seats are approx 68cms long, however the GT seat  shows the exposed loop,and the SF one sits on top of it as stated by Eabergman..Tank size?frame ?or just its design.

 

[Smartv11]

So, I wonder if a GT frame has a longer seat rails????

GT has a shorter tank, so a longer seat with greater distance between front holes and side frame mount lugs.

I believe there is a triple hump seat with the longer lug spacing so won't fit the SF frame without surgery.

I have what I believe is an early steel SF hump seat and the later fibreglass version, both cover the rear hoop (assuming the hoops are original).

and there are 750 seat which are wider at the front end, and even very early ones that plug onto vertical spikes instead of being slid onto rear facing spade lugs.

I have to redo the roof to my seat, I'd like to put molding on the rim. You have the measure of the height? The length should be up to the shock.

Thank you

 

[squalomediterraneo]

the extent of the molding should be about 33 cm, help me with the height?
Thank you

Thank you

I have one trim which is likely to be original for a 1970 'S' the length is 360mm and the depth/height c.9mm
