I guess you are talking about
this 996S differences compared to this bike
* frame colour
* wheels
* front showa forks should be titanium nitride coated
* The panels are from a 748 - the 996S bikes have 996 in silver not Ducati logo
Things that do look right -
* it's got 50mm exhaust all the way (no link pipe)
* brake disks look right
* rear shock
* tank
Get the frame number and engine number then you'll be able to tell. Reg number also you can do an HPI check.
If it's a 996S the frame number will start ZDMH100A
