Casey Stoner has confirmed he will not continue his tenure as a Ducati MotoGP test rider after the end of this year.

The former champion was vocal in his disappointment that the factory didn't use much of his data or feedback and the two parties have agreed to go their separate ways.

I want to thank Ducati for the great memories and especially the support and enthusiasm of the Ducati fans for our shared passion for racing and motorcycling, I’ll always remember this,“ said Stoner.

“Over the past three years I have really enjoyed doing my job with the test team, the engineers and technicians, as we worked towards improving the Desmosedici GP package and I sincerely want to wish the team all the very best for their future endeavours.”
