Hi again,
Piccy of OEM clip ons here:
http://www.ebay.co.uk/itm/Ducati-900...-/170970979436 But DONT pay THAT much....
OEM bars are pretty flimsy and rust prone.
Check out clipons from either a more modern (fuel injected) bike or look for good kit like Woodcraft, vortex or if flush, Harris etc.
or, you can make your own:
M&P accessories if I remember right.
