one piece axle for mk3 commando

The spacer, however, is static as it's a bearing spacer but the sprocket rotates.

Yes, you are right, the inner bearing rings and the spacer are static. I will have to endure the loose spacer.

The spacer would be in the oil/grease seal (item 25 but drawn on the wrong side of the bearing or see my previous picture) and that should help to keep it in position.

I did this using an axle from a Honda CB350. It's a bit long, but I just use some spacers to get the castilated nut in the correct place. It lacks flats on the other end to hold it when tightning it, uses a through hole instead, which requires you to carry a suitable screwdriver or similar to use as a tommy bar instead.

It's not a difficult project, but I don't think I would do it again if I was planning on keeping the original rear hub. I have a cunning plan to use a modern lightweight hub at some point though.

Tx for confirming that info, a way to use a cb350 axle as-is, prior info wasn't clear (or mixed).

Lotsa those out there & includes the 360 model (partzilla info already posted).
I forgot to include that JC also spoke against cutting/re threading an axle to fit. I remember one poster also saying cb350 or 450 (early 70s i assume) worked.

Then one poster went with yam RD400 (76-79 right) wheels that comes up on the 17mm rear axle list. That discussion included suitability of yam SR500 (78-79 right) wheels, hence axles.

Some of the axle info can show additional 'right or left' wording ..forget what that's about.

Prob some 17mm front axles would be suitable? & the last axle list/link (here again) i posted covers up to 97, there are a few out there.

For the complexity (extra double row bearing, et al) does the MK3 cush actually perform any better that previous models?

My understanding is a cush (far superior) that actually works, but even tho a bigger axle, is actually weaker (but easy fix available), due to breakage at the 1/2" thread area, also a disc brake.

Mighta been missed, no comments yet on this stumbled on it link

It really does a better job of cushioning than the early type. That's mainly because the earlier version doesn't work very well at all.

don't think it matters, fwiw, not an mk3....

Just took some measurements of my setup with Don's 1 piece axle:

Assembled total OD of my swing arm is 225mm (~1mm)
