I can provide the measurement this evening. I have a spare swingarm in my garage.

That would be amazing! I think it’s going to be harder that I think but a rough idea would be helpful, then I can roughly work it out

I'm curious to hear your ideas. I've wanted to replace the swingarm to reduce weight and to quicken the handling.

I've looked a several YZ swingarms, Ducati 900SS, and even TZ. All require more work than making one from scratch.

Sorry my bad it’s the inside swing arm pivot I’m after, wrong side! However that’s also quite useful!

I’m looking at at a SSSA from a ducati 1098, it would have to have new mounting points welded on to use the original shock mount. Or a really fancy push rod and pivot set up, but I think modifying the swing arm would be an easier route

Ah! Got it. I'll get it for you. Any other measurements that would be helpful?

Just that one should be good. Actually if you know the size of the pivot rod that could be help! I think it’s going to need a bit of frame modding. Will probably have to cut out the old pivot and weld in a wider set up.

Thanks again!

What do you mean by pivot rod? The brake brace arm thing?

I had a custom one built.

The rod or axle that holds the swing arm on the frame. Just the diameter, but it’s not all that important at this point!

This swap would work pretty nicely! Need some frame mods and swing arm mods! But it theres not a huge difference. Time to look on eBay for the right swing arm!

Thanks for the help!
