Anyone with a carbon tank may have two of these rubber fixing straps, Duc part number Strap: # 066083175. They are no longer availble from Ducati but I have recently found another source.
If there is any interest, I am happy to organise a group buy?
Interestingly, it looks just like the fixings on the front of my Harris TT2 tank ... and ones broken ... so if you can confirm the length from hole to hole, I'll have a few too. phil
