Works Ducati MotoGP team leader Andrea Dovizioso believes the factory have made an improvement in the Desmosedici's mid-corner speed with the 2020 chassis but says it is not yet enough.

The Italian has been demanding a chassis fix for several seasons and it appears the Bologna factory has come up with something, and Dovizioso thinks it's a move in the right direction.

“It’s a step forward because there wasn’t any negative points and this is good. But not that big. But we have to understand as much as we can because sometimes the improvement is very small but if you understand why you can have a margin to make a bigger step," said Dovizioso, speaking at the track.

“The important thing is to understand. It’s not that easy to do that. We have to be focused on that. We would like to improve a bit more in the middle of the corners. But we did a step so this is positive.

It will be very important to understand why we did a step to make another. That is the point. It was very interesting what we did with this chassis. But we need something more for sure."

Dovizioso is hoping to do more work on other parts today at Jerez as there are other areas on which he needs to work,

“We couldn’t test everything today but it’s nothing bad. The important thing was the chassis. We already compared. If we have some more time tomorrow we’ll be focussed on some other parts than the chassis.

“I think we have to study, analyse more the feedback from this chassis and make another step for the future. Happy about the improvement but not that big.

“The feeling is good but there are positive and negative things. The improvement is still not as big as we want but it’s quite normal because difference of chassis is quite big."
