Do you know why M. Marquez performed so well during his move to Ducati?
That's a very interesting question, and I'll answer based on what I've seen so far. Marquez came to Ducati when the bike was ready to go without any major overhaul. This also happened when Marquez joined Honda in 2013, when the Honda bike was indeed competitive and capable of winning championships in the hands of the right rider.
If Pecco moves from Ducati, do you think he will perform like the previous season?
Pecco Bagnaia is a rider who has provided more input to Ducati, enabling him to become two consecutive world champions on a Ducati. This means that Bagnaia is the type of rider who is able to provide input on his own riding, and this is not much different from his previous rider, Dovizioso, when he was with Ducati, even though Dovizioso never won a MotoGP world championship. And if Bagnaia moves to a factory team other than Ducati, I think he'll have to adapt more to the bike, as each bike has its own unique characteristics.
Furthermore, I once read a post from someone who frequently visits the MotoGP paddock, where he said that Aprilia tried to persuade Bagnaia to move to their team, but unfortunately, the clause he had to pay Ducati was quite substantial, as Bagnaia's contract with Ducati runs until the end of next season. So, we need to keep an eye on this in case there are any other surprises next season, as the news that's currently trending is about Toprak from WSBK moving to MotoGP.
