Word on the paddock is (Paraphrasing Ricard Jove here), Ducati allowed the GP23 to run 3 different flywheel configs, one of them that got multiple riders get close to the GP24 in performance; but that config destroyed M. Marquez’s engine in Mandalika, so they’ve limited the GP23 to only one configuration now.
It’s a config that M. Marquez can work with, but for all of the others it’s a big disadvantage. It’s bad enough for Diggia to consider skipping the remaining races to focus on his shoulder rehab.
Again, no official word on it, just Chinese whispers at this point.
