I need some technical information on the stock Showa forks on a 2001 S4. Thr Ducati shop manual states that these forks 43mm which is the size of the actual fork that goes inside of the stantion.. Does anyone no the outside diameter of the stantion I think it is either 50mm or 54mm. I am buying a new headlight assembly and need the size for the bracket to mount the headlight.

They're 54 at the bottom triple and 50 at the top triple.

Not sure where the transition is, I'll measure it here in a little bit.

The forks taper the top. The thickest part is where i need the measurement. I would do it myself but my bike is at the shop. The tech guy told me if it is above 2 inches around it is 54mm and below 2 inches around is 50mm. I beleive the 50mm measurement would be for the top triple clamp but the bottom triple clamp would be 54mm.
