I'm hoping someone could advise .
What size oil seal will I need to go in an M900 Clutch casing.
Been advised generic but need to know what to buy / look for.

It is to fit this casing .
Hope someone can help.

It's a 75 x 95 x 12 oilseal (metal) I got a generic one ages ago, then needed another a little while back when I got another cover to paint black and do a quick swap - I seem to remember that it's actually one of those (rare) Ducati parts which are surprisingly cheap, since you don't need them often.....
