Dovizioso was 'relaxed' during Ducati MotoGP winglet investigation

Dovizioso's victory was finally declared final earlier this week as the FIM rejected the appeal lodged by Honda, Suzuki, Aprilia and KTM after their initial protest against the Ducati device was thrown out by the Qatar stewards.

But Dovizioso says the winglet, officially in place for rear tyre cooling - although Ducati's rivals are adamant it creates downforce - did not have a material impact on his success.

"I wasn't worried about the points," said Dovizioso. "In the worst case, they didn't give us the possibility to use the piece in future.

"I wasn't too worried, because we [only] put that piece [on the bike] in warm-up. Also we don't have a lot of data about that piece.

"When you do something [like that], it's because there is something interesting, but we didn't have a lot of data about that."

Marc Marquez, Alex Rins and Valentino Rossi were all asked if they expected their respective manufacturers to follow suit and adopt a winglet of their own.

Marquez said he expects every manufacturer to trial a version but doubted its effect on the performance of the Ducati in Qatar.

"For sure [Honda] are trying to analyse," he said.

"They are trying to understand what is the function specifically [of the winglet] and where you can improve with that.

"I'm sure all the manufacturers will try. But I think it's not giving a lot of tenths."

Suzuki rider Rins added: "When one bike has a different thing, all the manufacturers are trying to do the same.

"I finished fourth in Qatar, I raced with Dovizioso, who had this spoiler. I didn't feel a lot of difference, only on the straight, but maybe this is for another reason."

Rossi said it would be "clever" to try to emulate Ducati but added he was unaware of any specific Yamaha plans to do so.

Ducati's device was in part inspired by a similar device used by Yamaha in last year's wet Valencia finale, albeit to disperse water, rather than to create downforce.

Maverick Vinales said this part would have to be redesigned for it to have a similar effect to the Ducati winglet when asked about the possibility by Autosport.

"What we have is for the rain, when there is a lot of water on the track to [disperse] the water before it arrives to the tyre, to not make this aquaplaning," he said.

"I don't think in dry it can make something [positive]. Last year we had something but not like Ducati, just to refresh the tyre, but it didn't make a lot of difference."
