Having been fiddling around with the back end of my 500 Strada for some time everything's back together but this spacer/tube is left on my workbench.

Does anyone have any idea what it might be please!?

In the pic it looks a bit DIY? I think there were some spacers invlolved with the seat catch and lock, not many survive intact though now. A spacer for a master cylinder mounting? Or a bush for a rubber mounted bit perhaps? Got a parts list to check through?

I can't say I recognise the spacer and like Steve said it doesn't look particularly like a factory part. It may be something cobbled up by a previous owner but I've no idea what for.

What intrigues me more though is, how do you manage to keep your hands so clean?

Can this be a spacer between the bearings of a wheel? Then the inner diámetro of a 500 rear wheel should be 17 mm+, for a 350 15 mm+.
It has nothing to do with the seat of a 500 or their lock System. I've just mounted one.

It looks familiar - could it be from inside the rubber suspension mounting bushes - like inside the tank mounting rubbers - just a thought - Duncan

mind you looks a bit too chunky now I look closer

Good question! My other hobby is stamp collecting so i need clean hands for that so i take the easy solution and always wear nitrile gloves while tinkering

Very sound advice!

If that spacer is anywhere near 17mm ID do not argue with a man with hands this large.

that' what I was thinking, looking at the foto the second time

As you were tinkering at the back, is it the bush that goes over the indicator stem to stop the rubber mount crushing? From memory, they are around 8mm ID, 10mm OD and around 12mm long.

I'll check, cheers

Have you had the shocks off? Inside the mounting bush?

This is the most interesting hint to me, in particular if you changed the skocks (otherwise you would have noticed if these are missing)

Yes, I replaced the shocks, cush drive, pads and disc and had a general clean up but its too small to be the insert for the shocks and they are attached firmly with no play at all. It's rides fine apart from a weak rear brake still. I think I'm coming round to thinking that it's a random dropped item that was wedged somewhere around the chainguard that just fell free as I took the wheel out...................or it was on the floor before i started from somewhere or another.

I just need to work out why the rear brake isn't bleeding properly and once that's sorted i'll be happy with everything
