907 ,320 mm front disc rotors, What a wicked bit of gear these things are, looks like at least 5mm to 10mm play side to side and 1mm to 2mm up/ down. I thought innocent bystanders were looking at my motorbike with an appreciation of awe but it was horror at the noise of the rattling "Free Floating" (into space) discs. Looks like more fun at the bank again. A mate has a 900 ss 95 model same discs and they are tight, are mine a lemon pair? or are they meant to freak everyone out?...Marty

That much ain`t possible, I think.
If you have floating discs, shim them to 0,4-0,5mm freeplay sideways.
Works good & quiet.

Thanks Gert ,how would you do this? ,can the discs be taken off the centres with tools or are they riveted or similar. I had a look but could not work it out, Thanks Marty

You do have floating discs?

If so, rivets can be removed & shims could be switched.
Quite expensive, like 4-5 Eu/shim.
I did this myself, not complicated, no special tools.
Just a locking washer f shims IIRC.

Thanks Again, Gert. Regards Marty

No problemo & good luck w this task.
Btw, it`s worth doing, if you doubt it...
