In late July 2026, former MotoGP champion Casey Stoner revealed that he had undergone major spinal surgery (L5‑S1 fusion and L4‑5 disc replacement) to treat injuries from a 2003 crash. At the Goodwood Festival of Speed he also said Ducati had never paid him for the technical assistance he provided to current champion Francesco Bagnaia during the 2025 season.

A week later, speaking at Ducati‑related events, Stoner reiterated his frustration. He was criticized by former rider Michele Pirro for using test sessions to showcase speed rather than delivering systematic feedback. Stoner responded that his contributions had been taken for granted and announced he would no longer share his MotoGP knowledge without compensation, noting that his recent back‑surgery limited his involvement this season. Bagnaia publicly thanked Stoner for his help in Ducati’s recent championship wins, highlighting the ongoing tension over recognition and payment.
