| I've dropped a toth on the gearbox sprocket on an ST4s, 996SPS and 996R (similar engine to yours), well worth doing, makes it more responsive and as Totto said top gear more useable.
When chains have been due for replacement, i've then put 15 tooth on the front, and gone for extra 2 or 3 extra on rear sprocket as its kinder/easier on the chain with a larger front sprocket.
As Nelly points out, an extra 3 teeth on the back needs a longer chain.
IMHO I think lot of Ducati's come geared too high, and its a very common mod which works well.
