Rizoma Rearset help please

[StephenC]

I've just installed my new Rizoma rearsets.  Mostly it went OK (apart from breaking a hex bit and burning myself on the exhaust as I checked things out after a quick test ride).  I have a question to pose to others who have done the same install, if I may?

On both sides there is a large 24mm nut, the top of the there that hold the rearset to the frame.  Between the bike and the new rearset there is a foam washer.  Between the rearset and the nut there is a rubber washer and a metal washer or two (one was OEM and one with the kit).  From the instructions it looks like the rubber washer (not the foam) is supposed to be loose, is that right?  On the brake side I didn't need the Rizoma metal washer but I did on the clutch side, to stop the nut squashing and deforming the rubber washer.  This set up leaves the foam washer both sides loose, as in I can spin it freely and it doesn't really press up against anything tight enough to for any sort of seal.

Am I doing something wrong?

Diagram below to (hopefully) explain what I mean:

There's a shoulder on the swingarm shaft.
It's there to avoid contact between rearset and swingarm, as the swingarm moves and the rearsets don't.

You should use spacers, or not, to ensure a .2 - .7 mm clearance between the large OEM bolt and the rubber.
That leaves the rubber free to rotate with the swingarm shaft.

Maybe you can tell us, or even post a picture, if the rubber has a metal tube inside it.
If it does, that's certainly what is going to rest against the swingarm shaft shoulder.

That makes sense.  I hadn't really thought that the swing arm and frame move independently.  Now I look at it that rubber washer makes sense.  My combination of 2 metal washers one side and one the other seems to leave a nice small gap either side, which seems perfect.

This is everything in place:

You can just about imagine the rubber washer is loose.

An exploded view of the bits I could be bothered to dismantle (it would be too much hard work to take the whole rearset off to show the bit the diagram describes as a 'spacer'):


And where they go:

The larger metal washer fills the defect between the end of the 'spacer' and the outside edge of the rearset.  The smaller OEM washer fits inside the rubber washer.

That sounds and looks fine to me

Thank you

Yeah I kind of had the same problem too. I think I ended up using the stock washer on the right side and using the Rizoma washer on the left side. I know the rubber wasn't squished this way. Miunno, seems fine to me.
