Hi Stu - Welcome on board.
Nice looking bike you have there - can't believe someone here has not made you an offer for it yet for Desmodue (like a swop for a 750
).
Sadly, the book I have does not mention the 600ss ever being produced with a white painted frame so, sorry - yours might well have been fully rebuilt at some point.
Single seat:
As Chi mentions Diopa and others produce some nice full single seat conversions however, Ducati themselves still produce a cowl that goes over the passenger part to make the back end look nice - I bought one from Ducati Leeds for about £50 a few years ago.

Very personal but I'm told that (even though I have them myself) Diablo corsa's are over kill for the road and that the standard Diablo is just as good and a bit cheaper.
