New genuine Ducati carbon cans. 
For sale after only 2000 miles use. Almost mint condition. These are the race variety, not road legal. Will fit ST4s & ST4. They do not need an ECU change, but the injection should be re-tuned for correct CO2 emissions.
I’ll add an image asap.
They could be converted for use on 900ss. 1000DS or similar bike.
Cost new; nearly £600. All sensible offers will be considered.
