Petronas SRT's Quartararo gets '19 MotoGP bike in Yamaha U-turn

The Petronas squad, which replaces Tech3 as Yamaha's B-team in 2019, had originally planned to put Moto2 graduate Quartararo on a 'B-spec' year-old bike this season.

But a late decision was made by Yamaha to supply its satellite operation with two 2019 machines for its first MotoGP campaign, meaning Quartararo joins team-mate Franco Morbidelli in having the current bike at his disposal.

Morbidelli will still be prioritised for upgrades handed down by the factory team and is set to receive upgrades two races after they are debuted by works pairing Valentino Rossi and Maverick Vinales.

Quartararo will also have fewer engines at his disposal than Morbidelli, with a slightly reduced rpm to extend their life as a result.

"That Fabio will have a 2019-spec Yamaha is a very good sign, and indicates Yamaha's mindset," team manager Wilco Zeelenberg told Autosport.

"It's something that has surprised even Petronas.

"It relates to the engine and other components, in addition to the upgrades. Fabio's engines will be a bit more limited than those of the others, but that is normal because he is in his first year and has to adapt to the category."

Morbidelli and Quartararo both made strong impressions in post-season testing last year at Valencia and Jerez, with Morbidelli ending up sixth overall in both tests.

On the opening day of 2019 running on Wednesday in Sepang, Morbidelli was 12th-fastest, eight tenths slower than pacesetter Marc Marquez. Quartararo placed 18th.

Zeelenberg added: "These results would have been impossible without Yamaha, which from the first day has been helping us.

"In Valencia and Jerez there were 10 engineers from the factory in our workshop.

"Petronas is not here to survive, to let the years go by. It has entered the championship the way it did in order to win."
