I'd like to consider a single seat with rear carrier for my T100S. I've seen Meriden and Hinkley Bonnevilles with single seats, like below but how about 500cc unit bikes? Would I still have easy access to oil and battery?



I figure Ted Simon's single seat on his T100 must have been comfortable enough...

Hi Matthew,

Ime, the basis of a single seat seems to have just been the front part of a standard dual-seat pan; however, in the case of the T100P and police version of the T160 I've seen, you need to use enough of the pan to be able to use the seat catch and an additional hinge pin was added to the frame. Some T160's had a clamp-on pin but others, and police versions of the twins, all seem to have had the frame drilled and the additional pin welded/brazed in like the normal two for a twin seat. Also bear in mind that the two hinges for a twin seat are different so I don't know whether the position of the additional hinge pin is dependent on which hinge you use? And then you'll need to make an additional clearance cut-out in the top of the sidepanel?

Then the basis of your rack could be (a copy of?) the police-version radio mount?

But I'm wondering what your thinking behind this is - on the face of it, seems a lot of work to make a less-flexible bike?

Hth.

Regards,

I'm in the process of making a single seat out of a dual seat for my T100 ISDT bike which is a 68 Daytona. Having to invent all kinds of things. I shortened a damaged dual seat, bolted it together and got welding done, only using the front hinge so far, have to move the piece that goes into the catch on the right side to a new position, making blocks out of hockey pucks for the seat to sit on the frame, had to cut out the rear bottom of the pan to clear the rear fender, making a catch at the left front of the seat and then I'll have to cover it. It's been quite an adventure but I'm a determined cuss and I might even put a zippered tool kit in the bottom of the rear of the seat Peplow style if I really feel ambitious. Building a special requires the services of the Meridan comp shop or more time and money than it should and it's not as straight forward as I would have liked it to be but it's more fun than an original type restoration. But that's just me......Cheers, Wilf

I was hoping to get a more comfortable single seat, not just mod a standard dual seat.

I believe Ted Simons bike was a P or Police model.

Matthew, no need to move the rear seat hinge pin on the frame.
The Triumph "Saint" used a solo seat, and it hinged like the regular dual seat, but the factory made a special rear hinge pin to move it forward. The mount was a plate bolted to the upper left shock absorber mounting bolt, with the curved seat hingeing pin welded to the plate.
Will someone with a "Saint" please put a picture of this mount on
this site so Matthew can see what it looks like?

Here's an image of what I had in mind...







I figure I'd find such a seat, fill it with gel or other good padding and use it for longer runs, with more space for kit behind the seat - maybe put a carrier rack back there.

Food for thought: I've engaged the same thought once or twice, an option you may not have considered is location of hinge. Why not flip up backwards, permitting you to mount the hinge on the rear of the solo seat, and on the fender? Another option would be a forward tilt, possibly using the rear tank bolt area as a spot to mount the front half of the hinge? By mounting on the rear of the seat, it would easily enable using a standard seat pan cut shorter, as the basic curves are already there- bear in mind clearance for the seat padding and cover. (Honda CB450 used a rear mount hinge, worked quite nicely.) Either front or rear mount does leave the problem of a seat latch for securing. Again, the CB450 seat latch is very close and could easily be modified for the purpose.

Hi Matthew,

Mmmm ... I used to have similar thoughts (about different parts) ... In practice:-

. at the other end of a "longer run", I'd need the flexibility of the part that was back home;

. I'd get back from a "longer run" and need the flexibility of the part that wasn't on the bike before I had the time to change them ... frown

Ime:-

. I would modify either the whole dual seat, or just the front half - I'm currently experimenting with layers of different-density foams (as Honda did (do?) as standard; ime, their standard seats are still comfy when they're years old). With care, even original Triumph cover clips and trim can be removed with little or no damage - with a pattern seat, clips and trim should be available.

. You hand over a seat pan to an upholsterer and say, "I want a, b, c"; it comes back, you try it, you don't like it, what are you going to do? Hand over more money to the same or another upholsterer?

. Otoh, diy and you can change it as much as you like for, at most, the cost of the parts and your time. Do the work in the warm and, with only a little practice, no-one looking later will even know the seat has been fiddled with. bigt

If I'm one-up, I just use one of these to strap stuff to the seat behind me.
