Andy,
You could give these guys a try -
BVM Moto. I don't know if they actually have the one as used by Ducati in stock but you can get the specs and part numbers off the
Red Racing Parts website so being a Domino dealer they should be able to get one in for you. Might work out a bit cheaper than buying from Italy. Having said that, apparently Red Racing Parts are very good with excellent delivery service.
Cheers, Neil
