OIF Question

[CarlS]

Ah, the intricacies, variations, and changes of vintage Triumphs. And these can occur within the same VIN sequence.

 

[Dschief]

If you think about it, the NX (October) bike could actually be called a 1979 model, if you follow the September = new model year theory.

So, after frame number BX5107 the shocks should be upside down.

My serial number is T140VNX01191

It take it that means that mine is after BX5107....correct? The T140V part is the model.

So your shocks are now on the wrong way

 

[CarlS]

He could put one on one way and the other on the other way. Then he would always be half right. :ya2:

 

[DaveM]

:y24: But then he would only feel half as good

 

[Dschief]

One might say he was riding half-a$$ed.

 

[Rocky]

And half wrong :y114:

 

[CarlS]

AJ, we wouldn't get off topic around here. :y114:

The bike actually feels more stable with the shocks on the way I have them now.

Who knows if these are the originals or not too???

 

[DaveM]

I would actually like to know what the change was and why they turned them around

Likewise. I'm afraid that is one of Meridan's many mysteries.

 

[DaveM]

Now just think every time you now ride the bike like that you will be thinking "My shocks are upside down hope no one notices" h: :y24:

 

[CarlS]

He will be OK as long as he keeps the bike right side up!

 

[DaveM]

Yes true. I wonder if the change was a structural change of some sorts

 

[CarlS]

Who knows?

The Girlings were the old "standards" with the hydraulics valved for use at the bottom, with the rod on top.

Koni came out with a new design that needed to be mounted "upside-down" for whatever reason. I suppose some engineers get an idea in thier head, and that's that. I think those were 79 only, or maybe 79/80. Then came the piggybacks with remote reservoir.

 

[The Seeker]

Looking at the frame(s), I see absolutely no difference between the two serial numbered frames. I think it had more to do with a redesigned chainguard (no longer curved) which would rub against the spring if you put the shocks on the normal way.

 

[DaveM]

AJ that would then make sense so it must have been a workaround on Triumph part to solve that issue

Hi Listers , I vaguely remember a tech article way back then that claimed that the Koni shocks used nitrogen & some sort of "paste" for damping and this required them to be mounted upside down ......

Somewhat dazed & confused these days ,
