Sorry, should have mentioned this is an '07 695!
You may have to make a replacement.
If you do that, IMO it'd be prudent to come up with a better mount.
Termi took advantage of the threaded fittings for the seat lock with that design.
Trouble is, those mounts were sized for holding the seat lock, not half of the exhaust.
It's a janky setup at best.
I agree, the right side setup is pretty crappy. They should have just made one bracket that goes all the way across!
Anyway, I called the dealer yesterday, and the part isn't available from Ducati.
So I brought it to work today and asked our welding guy if it's fixable, and he said probably! I'll check back with him tomorrow and see if he was able to get it fixed.
