Ducati CEO Claudio Domenicali commented: “Casey is and will always remain in the hearts of Ducatisti and it is also on their behalf that we wish to thank him for the important collaboration he has offered us over the last three years. His technical indications and suggestions, together with the work and the feedback of the factory riders and Michele Pirro, have helped to make the Desmosedici GP one of the most competitive bikes on the grid.
