Of course MM is better on worn tyres than pretty much anyone, most of us watched his 6 title wins and many race wins.
But why couldn’t he pass Morbidelli, a light of other days, on new soft tyres ?.
As I have said I strongly suspect Gigi is a rather good engineer/ designer, and is likely not to have wasted years of his time and a lot of money to produce a bike which is no better than the GP23. The guys who have raced both bikes say the GP24 is better, and the Ducati test rider whom you cited as a supporter of your point of view is on the record as saying he is unhappy about the prospect of MM getting upgrades. Is he trying to help MM by restricting him to the superior bike perhaps ?. It is also a vague possibility that Digi is better informed than you or I am as an actual current Ducati GP rider particularly since they apparently see each other’s telemetry/data. And why is Gigi so impressed about MM’s performance on a GP23 concerning which he has been quite vocal.
Top speed is a discussion between you and one other poster as far as I can tell, but the overall package will have been designed to be superior, possibly with trade offs between top speed and rideability, acceleration etc, but I see no evidence whatsoever that a GP23 can pass a GP24 on the straights. The KTM perhaps can but is fairly clearly deficient in comparison with the Ducati GP24 in other facets of performance. We had this discussion before with the Ducati GP07, the bike that rode itself on which Casey Stoner could apparently just blast past his competitors on the straights and snooze the rest of a given lap, Turned out he was the only one who could get the thing through corners at all, and only by a quite extreme method.
Again, why was MM on fresh soft tyres stuck behind Morbidelli for quite a number of laps ?.
