Valentino Rossi came into the Aragon MotoGP weekend warning of a tough event for Yamaha.

As the heat rose in the Spanish desert, so did the frustration within Tech 3. Johann Zarco’s woes were such in MotoGP FP2 that he even began questioning his own ability as a rider.

Valentino Rossi doesn't believe changing the MotoGP engine-freeze regulations would solve Yamaha's current acceleration woes. Unless a Yamaha rider wins at Aragon this weekend, the factory's losing streak will reach 23 races, its longest barren run in MotoGP.

Ducati and Honda learned from Yamaha by taming their MotoGP machines to mimic the smoother riding character of the M1.

And so the winless streak stretches on. Maverick Viñales was at a loss to explain Yamaha’s lack of competitiveness in Sunday’s MotoGP race at Misano in which he was “sliding all corner” and overtaken “as if I was stopped.”

Valentino Rossi began race day at his home Misano round hoping to fight for the podium after a competitive pace in Saturday's final practice.

There was little joy to be found in Johann Zarco’s Sunday afternoon at Misano as the Frenchman encountered familiar issues with acceleration while struggling to a disappointing tenth place finish.

Maverick Vinales says Movistar Yamaha breakthroughs from last month’s Misano test on its electronics package has restored confidence with the YZR-M1 but accepts the team will have limitations with its current engine for the rest of the season.

MotoGP FP4 may have brought about a significant improvement with the feel of his Yamaha M1, but Valentino Rossi is still chasing “two tenths” to conjure up a podium charge at his home grand prix at Misano.

Vinales sets the fastest lap time during a closely matched (and sunny) final practice at the San Marino MotoGP. Qualifying 1, for those outside the top ten after third free practice, will now get underway.

Valentino Rossi and Movistar Yamaha team-mate Maverick Vinales have welcomed the news that 2017 MotoGP podium finisher Jonas Folger is to become the factory's new European test rider .

Friday’s on-track action at Misano confirmed enjoyment had returned to Maverick Viñales’ riding as he ended the first day of MotoGP free practice with the fourth quickest time, leading to to a belief that a podium on Sunday is well within reach.

Maverick Viñales believes a small set-up change at a private test has allowed him to re-find the feeling that has been missing through most of 2018, and is hopeful he can continue his recent resurgence at the 13 th MotoGP round of the year.

Josh Brookes says given the ‘disappointing’ progress to his 2018 Bennetts British Superbike championship his sole focus remains on victories between now and the end of the season while he won’t consider a conservative approach to reach the top six spots at Silverstone.

The Christophe Guyot-run GMT94 Yamaha squad will make its full-time return to the World Supersport grid from this month’s Portuguese round before a full 2019 campaign.

Johann Zarco says he will continue to target the top five at Misano but concedes missing out on the recent test at the Italian track may hamper his efforts for Monster Yamaha Tech 3.
