The one here has ID = 92mm, but it is evidently changed to suit an adaptor for use with a wide tyre which is no longer to be used. The sprocket carrier is also modified unfortunately, down to 88mm. Does anyone have a spare carrier they want to sell? Otherwise I'll have to restore this one, which I'd...

Can someone kindly confirm the inside diameter size of the rear sprocket?
It's a 1989 model 906.

Also, the owner's manual says it has 41 teeth, but the parts book says 40.
Is there a well accepted preference?

Thanks,

The brand Flennor has been mentioned.
Do others agree this a safe choice?
Someone in Germany has service kits that include them, as well as filters etc.
It would be convenient to get the complete kit.

Anything special about these, or will any good brand of the correct size be OK?

Are there any recommendations or otherwise for 906 Paso parts in Australia?

Thank you for the detailed answer, very useful.

The Paso 906 here has the clutch slave cylinder on the right.
So, a Paso 750 sprocket cover should be OK.
Thank you for the info.

750 and 906 Pasos have different part numbers for this part.
But can one from a 750 fit a 906, or is there an important difference?

Hi Folks, I need some info.
How is the swing arm pivot on a 906 lubricated?
And, what is the purpose of the two screws, above and below the right side pivot?
