XS2 Forks vs 1974-1977 Forks for XS2 RESCUE

[fermatseye]

I recently rescued a 1972 XS2 from the scrap yard and am piecing together a ridable bike. HaHA I feel funny saying rescued, where I live everyone introduces their dog as a "rescue", which really means they came from a pound. The forks are locked, the stanchion tubes are shot but the sliders are still A-OK. I have many other parts for XS's laying around but I want to keep the front wheel/brake setup from the XS2 original. Will stanchions and other internals from a set of 1975 forks work?
I should get some pictures of this beast up, she's homely and I love her. Rolling chasis with the tank, NO DENTS in the tank even though it was laying in the mud next to a pile of iron getting grabbed up by the larger than life amusement game claw. This bike sports a gnarly sissy bar from the early 70's and will be a great rat-ride. Then traded a pile of XS750 engine parts for a bunch of other XS2 stuff, but no forks.

Here we go:

You are crazy,, but then, we all are.
1972 to 1975 forks are pretty much the same.
In the tree, Use the new tapered bearings, should the old ball bearings, be bad. (which they are not, all that good, even brand new)
The 1976 forks are the same size, but the disk brake location, in on the "leading edge" , not trailing edge.
1977 and newer, the forks have bigger diamater tubes, better interior valving and stronger brake caliper.
( and swap right over, but you need to deal with dash/gauge mounts)

At a glance the spindle diameter is different for the two sets of forks I'm talking about, that's what led to the questions.
The forks that I'm calling '75 came off of a '75 but I guess that doesn't mean for certain that's what they are. Could be a later model...
This may call for more pictures.

BTW who told you I was crazy?

I also go to junk yards, and buy stuff, that i should leave there.
So we know we are crazy,,,, but as the lady in church said the other day,,, you know,,
You never see a motorcycle parked in front of the psychiatrist office, do you?
So, maybe our disease, is not as bad as some others.

as far as your 'spindle' , look at the application, on mikes XS it only list the front axle Part #49-0727 for 1974 to 1984, so you may have a point to be concerned about, with using a 72 front wheel, on 75 forks.
You may try looking at parts sources, and look at axle bearings and such. (for the years you want to swap)
Try it, and let us know.

Right, the 72-73 front end (XS2 and TX650) is different from the 34 mm. front end used from 74-76. The parts books at www.biker.net will show you the differences.

Right. And you never see a motorcycle parked in front of the old folks home either. They take it away from you when you check in, so ride it now while you can...

I ride my bike to the head shrinker. I park out front.

Hopefully, your bike is faster now,,, with less wind resistance, when you have a smaller head.

The 72 was a one year only way of mounting the brake rotor to the hub. If you want to save it rebuild the forks you have.
If you want to use a 75 fork just use a 74 up front wheel. These have bolt on rotors and use one less bearing.
