Some dismiss Ducati’s problem by saying, “Stoner won on those Ducatis.” Casey Stoner won the MotoGP title in 2007 on a steel-tube trellis-chassis Ducati, during the era of hot competition between Michelin and Bridgestone. Since then, Ducatis have changed, tires have changed, politics have changed. And although Stoner won a few races on the evolving Ducati, he won no more titles until he switched motorcycles. In his first year on the Honda, he was champion again. Somehow, Ducati, whose bike astonished the paddock by winning a race in the company’s first GP season since 1959, is now unable to lift its finishes much past sixth place.
