Andrea Dovizioso: MotoGP rivals outdeveloped Ducati in 2019 season

Dovizioso, who scored four wins on his way to second place in the standings in 2018, sits 58 points behind Honda's points leader Marc Marquez at the midpoint of the '19 campaign.

The Ducati rider took victory in the season-opening race in the Qatar Grand Prix but has not finished on the podium since the Italian GP four races ago, while Marquez has won four of the last six races.

Dovizioso feels that while the Marquez/Honda package has got stronger, rivals like Suzuki and Yamaha have also out-developed Ducati so far this year.

"It's not so much that our bike has not grown enough, it's that the competition has grown more than Ducati," Dovizioso told Autosport in an exclusive interview.

"The Honda and Marquez package is stronger, the Suzuki riders have taken a step forward and their bike has also improved.

"The Yamaha is more competitive than last year and all that. With all the skilled riders we have in MotoGP, nowadays the championship is more complicated.

"So instead of being stronger in our fight with Marc, we find ourselves in a situation in which we are struggling.

"Marquez is fighting for victory in every race and some riders are often faster than us."

Ducati's main weakness with its recent bikes has been turning-based, something Dovizioso acknowledges does not have an easy fix.

Asked why it has been easier for Honda to solve its power struggles while Ducati has not been able to sort its turning, Dovizioso said: "Technically it's a lot easier to gain power because the thing about making progress with the turning is that it's a combination of many things. There's no perfect recipe.

"Increasing the power is a different thing, it's easier."

Dovizioso feels five-time champion Marquez, who has won the title for the past three years, is currently riding better than at any point during his career.

"Marc is a very strong rider who also never stops learning," he said. "He doesn't have ups and downs and [he is] a rider who is always improving, he never goes backwards, he always stays where he is or gets even better.

"Almost all of them [the other riders] are going backwards. Most of the riders have those ups and downs.

"But the good riders, the smart ones, might improve more or less, but they never go backwards."
