Stock swing arm length

[Jfraser06]

does any body have the measurements for a stock swim arm length?!

It's in here somewhere.
Maybe a forum search on "swingarm inch" will find it...?

Everything I’ve found was about extensions, no exact measurements of a stock swing arm

 

[X77S]

I think I read there were length differences between some years.

I think X77S is correct. I think there were differences between earlier/later models. I have a '75, '79, and an '81. They appear to be about 99% interchangeable. I have the swing arm out of "The Basketcase" ('75). Unless someone has a fast answer, I'll measure mine, next time I get to the shop. Would center of the pivot to shortest point of the axle plate work for you? I was planning to have it "stretched"...

Here's a pic of my swingarm, for reference.
From the pivot center to axle center (axle full forward).
'71 XS1B swingarm length = 16.5"

That should be the same for all 70-73, XS1, XS2, TX650 models.

74-on swingarms should be 1.5" longer, at 18".

We'll let 59Tebo confirm this...
