I could not find a table of dimensions in Guzziology. Don't know if your bike and mine share the same springs. Mine is '04 Cali EV.
Length 14.75" or 375mm These could have compressed in service.
Outside Diameter 1.515" or 38.5mm approx
Wire Thickness 0.215" or 5.5mm approx
Note Imperial measurements for the last two are more accurate
Hope this helps mate.
