Peter, try part number 6104881A, call Craig at Moto Rapido on 01962 873981 to confirm, they are available in the uk for less than £20, for ref and if you are not in a hurry https://www.ebay.co.uk/itm/Ducati-B...594874?hash=item23b997e4fa:g:bKoAAOSw~~Nco3Qr
I wondered what the elastic band in the kit was for, answered in the video of the replacement piston recall in post 65! Ten minutes with no movement
ok, but I think that kit only fits the later style 16mm piston as used with the Brembo M50 calipers, mine is the 18mm I think, but need to check
Hence the advice to call Craig at Moto Rapido to confirm, we can't all be aware of which version and MY of Multi you own as you don't specify.
