I see wear/damage on both. The one flange has both shoulders worn (with very small resulting surface area, as you noted), the other side has wear on one shoulder.

Like you said, with that small amount of mileage, the only way this kind of wear should occur is if there was no (or little, or the wrong) lubricant in place. Perhaps someone removed the proper moly grease with a tire change at around 5,000 miles and ran the remaining 15K with the wrong grease? That would certainly do it.

Like you said, the only fix is replacement, so you'll be looking for bike breakers or eBay.

That does have a fair bit of wear on it - you might get lucky - do an ebay search on the PART NUMBER - I think you will find that part was also used on some other Honda models - so rarity should not be that hard to find another one in good condition.

I had my old one - it was worn to points on the flange - and had a serious amount of backlash.

See if I can find some photos for you.

Found the topic I posted some time ago - it shows the relevant photos for comparison

So I sourced another rear wheel flange. Splines look great. It is off a '82 GL1100. Surprisingly it was one of the cheaper ones on e-bay. It is tough to buy used parts, as the pics don't always really show true condition.

new (used) flange.  splines look good.
new (used) flange. splines look good.

But I have questions. The pins look different. ( see pic below ) They are machined with a slight relief area in the middle. On e-bay I noticed many of the used flanges had this same style pin. I assumed it was just a newer design since they all have the same part #'s ('80-'83). Do you all agree ?
But then I started to mic the new part vs. the old. Most critical dimensions were a match. I proceeded to try to determine any "bent pin" condition. I measure all 5 combinations of pin to pin span across the bore. There are 5 pins, so they are not on true "diameter" relationship across the bore. At the base all 5 measurements could be grouped within a .003" cluster of data points. Same on both parts. I then did the same measurements near the tips. The original part showed a small amount of deviation from the base measurements. They fell within about about a .005" cluster of data points. So then I did the same for the new part. There was a little more spread... they fell within about a .008" cluster. So the question: How much "pin bend" is tolerable. They go into 5 rubber bushing type holes, so how precise do they need to be? Should I try to tweak them? Or should I try to move the old pins to the new flange?
This leads to one more question: The new flange has had the lock nuts removed. The old flange has lock nuts but they are "crimped" so as to be very difficult to remove. Has anyone removed these ... how difficult? Would one end up bending the pins trying to lever against them while wrenching the nuts. I figure it would be easier to get new nuts rather than reuse the crimped ones. Should I use locktite since I have no way to crimp the new nuts. What torque value on these?
Lot of questions... but you guys have been a big help here.

pins are different.  need locknuts on new part.

I would get some new nuts - and then use red loctite on them. Not sure of the torque required, but I did mine up as tight as I could get.

Put some moly paste on the pins - but refer to the service manual first - I think there are a few models where there is no grease applied..

That is a good looking flange..nice pick up.

My 1982 GL1100 had the flange with the indentations in the pins, and locknuts:

To my recollection, the flange without indentations (like yours) is from a GL1000. However, GL1000 flanges have six pins, not five. I wonder if yours is a bit of a franken-flange?
