Ducati's Petrucci must manage MotoGP races better for podiums

Petrucci had an up-and-down weekend at Termas de Rio Hondo, starting off with the "worst day" of his brief tenure as a works Ducati rider on Friday, before finishing sixth after qualifying in 10th.

That meant he finished three places down on his team-mate Andrea Dovizioso, who has scored both podiums in the two races to date compared to Petrucci's zero in his debut factory Ducati season.

Petrucci says he must learn to pace himself more strongly in races.

"I'm trying to find a riding style that doesn't consume the tyre," he said.

"But on certain occasions, like here [in Argentina] where there are long corners on acceleration, to put more weight on the bike that slides makes me consume the tyre more. So I must make up the time in other areas.

"Sometimes it's a benefit because I can straighten the bike with more weight and have more grip. But when the bike is still leaned over I have to be so careful with the throttle.

"Here that happened a lot, they passed me coming out of Turn 6 and into Turn 7 because I had to save the tyre. In the end, it was not enough to save the tyre.

"I would have preferred to finish fourth, but I started 10th and I wasn't handed anything by anyone.

"I want to do more, but to do this I must improve in managing the race." Petrucci added that he is still learning to battle the top riders in MotoGP.

"The riders in front of me have several world championships and many victories, I have neither, so it's difficult to fight with them, it's difficult to trick them," he said.

"Even when they seem to be in trouble, they always seem to have more margin, but I never have it because I always have to come from behind."

Petrucci said he is expecting another tricky race at Austin next weekend before the championship returns to venues more traditionally suited to the Ducati.

"It's very difficult because it has tight F1-style corners, and it is full of dips and those in the first parts are very annoying," he said.

"There is not much grip and it's very hot, it's not among the riders' favourite, except Marquez unfortunately."

Zarco won't change riding style

KTM's Johann Zarco said he was "exhausted" after MotoGP's Argentina Grand Prix after struggling with his bike.

He finished 7.7s behind 10th-placed team-mate Pol Espargaro in 12th but says he will not change his riding style because it will be essential in the future for KTM.

He explained that his smooth style means the bike is sliding around, proving hard to slow down under braking and is struggling with turning because "everything I do [in my movement] is not working."

Asked if he could learn from Espargaro's data, Zarco said: "For me, it won't be the key to then make the big step that will be necessary for the future [at KTM].

"I want to keep also my smooth and clean style and from that [and] see where we improve."
