I am not really sure of the part number. It could also be 0622-59-200 or 0689-59-200. The Ducati singles parts books are incredibly difficult to understand sometimes.
These struts were given to the customer when he or she bought the bike. Their purpose was to convert the machine to hard-tail, thereby making it class C legal in certain areas. Now they're just bad-ass cool.
C-C length is 265mm, about 10 3/8". The struts listed are BARE, but I have shock grommets listed here somewhere, in case someone needs them.
