851 SP2 frame number?
 

Hi,
I have bought a 851 SP2 transformed in a corsa model in its first year of life and it's like a factory 1991 corsa bike.
I would like to be sure that the number of frame is a correct sp2:

ZDM 888*six numbers*
DGM six numbers M

Please owners of Sp2 reply to me.
Thank you very much
Lorenzo

Any pictures of your bike?

Ducati factory confirm me that it's an original Sp2 and that said me also the date of production. I love it. If someone need information about frame contact the tech service online at www.ducati.com.

My 1990 SP2 has ZDM888S *six numbers* and DGM six numbers M, so yours looks OK. I'd love to see some pictures
