Alloy rim restoration

G'day All,

Anyone got any tips or advice on how to deal with restoring a 1985 XR600RF rear rim. The problem is the bloody thing is a 2.15 x 17 and aside from the XR350 nothing else I know of was shod with them and as such finding a good condition replacement is proving difficult. I could go to an 18" but then I may face the dilemma of matching spokes to hub to rim

The existing one has some internal (under the tube saver band) intergranular corrosion and has started to exfoliate, still structurally probably 80% of new. Problem is the external surface has a lot of tyre lever marks, the surface is also a brushed aluminium anodised finish.

Short of finding a good second hand one (no one seems to make a 17" anymore) I have a couple of options as I see it.

1. Remove the surface anodising and re-anodise.

2. Remove surface anodising and polish the aluminium finish.

Tips anyone?

CLICK Is it a 36 spoke rim?

Might be a bit flash/exy for what you want.
Might not even suit, I know there's other things to consider when it comes to rims.

Also, that rim was used on 7 models.
83/84 XR350 & XR500
85 XR350 & XR600
87 XR600

Might pay to give Phil at Lightfoot engineering a call. (03) 9898 3677
He's expensive, but he really knows his wheels.

Don't paint it or powdercoat it, that's the best way to make your bike look like a Chinese shitbox. If you've unlaced the rim, give it to aluminium guru like Dico to brush it up nice. You could always get someone to brush it up nice (DON'T polish it) you could then have it anodised silver so it looks original.

Exfoliation of the rim inside the tyre leads to flats, I would always find particles of rim imbedded in the tube.

how much are you willing to spend ?


US ebay have them


I have a 17 inch off an xr500 - but it has tyre lever marks - so I went with a whole wheel off an xr350 - a little bit narrower at 1.85 but still works

Caustic soda will easily remove anodizing.
Available for few dollars at woolies in the form of draino.
Mix a bath up and soak for a few minutes and it will dissappear.
I would then polish but that's me. I polish everything (keep it out of the gutter!)
Polishing can easily be done at home and depending on how much time you want to put into it you can get awesome results and can cost as little as a few sheets of wet and dry and a tube of autosol and away you go.
There is upkeep with polish. So if you are not wanting a finish that will require maintainance then clean up and re anodize.
Agree definately no paint or Powder it will go to crap.

Some good info there.

Painting and powder coating were never an option though.

Re-anodising is a possibility but the existing scars are deep so by the time they are polished out along with the corrosion I am getting down on material and strength. Aside from hopefully being a nice example of a great bike when completed it also needs to do Finke and back this year.

I have just decoded the Honda part number riddle and it appears options are opening up, namely to acquire spokes that will allow a lace in of an 18" rim on the 600 hub. An 18" rim opens up tyre choice and also a new rim option and it appears the 89 model 250 has the same hub as the 85 600 but with a 18" rim.

If money were not an option none of this would be an issue, but like many, times are tight at the moment.
