Valentino Rossi completed his fi𒁏rst l💦aps with a prototype of the 2020 M1 during Monday's official post-race test at Brno.

With Yamaha playing catch-up to its leading MotoGP rivals, Rossi was pleased to get an August debut on next yeඣar's machine "like in the good 🔴old days".

However, the Italian also emphasised that it's very much a first version and, at present, not much has changed over ꩵthe current machine.

"It was a good day, a good test," said Rossi, who set the sixth fastest lap time (+0.399s) after finishing sixth in the race. "We tried also the prototype of the new bi♛ke, but sincerely we don’t have a lot new

"It's a different engine and a little bit different setting of the chassis. But i🃏t's just the𝔍 first touch and we can have something else also in the next test.

"It's already good that we ⛎have [the new bike her🅘e] but after we worked more with the standard bike."

The main difference for the new carbon-🃏black bike at this stage is a revised engine, with Yamaha lacking clear str🌼aight-line performance against the likes of Ducati and Honda.

But again💃, fꦆor now there is not a big change.

"We don’t feel a lot of difference, no," Rossi said of the engine. "But ꧟we expect because it's just a little bit different in the engine.

"But this is not the 2020 bike. It's just the first prototype," he emphasised. "And we will work, w🎃e will try something else, but we need more for sure."

On the chassis side, "We try to have more grip, especially from the re🔯ar, so we try some different settings because 🐲for the rest the bike is the same.

"And we find something better, something worse, we fight a little bit with the wheelie. So we have a lo🍎t of work to do still.

"But it is just the first touch, we have a lot to do and I think that the Misano test, after Silverstone, will be impo♚rtant for everybody because we will have something else. But anyway it was๊ a positive day."

Rossi, seeking to end a win drဣought of over two years, also tried a revised seat unit and new fairing on his standard bike.

"It is the first prototype for next year, t✅o try like always for less wheel🎐ie," he said of the fairing.

Engine design cannot be changed during the season, whil🌟e Yamaha has already used it's one available 2019 fairing upgrade.

Team-mate Maverick Vinales also had a brief run on the new bik♌e on his way to the second-fastest lap time behind rookie Fabio Quartararo, whose team-mate Franco Morbidelli completed an all-Yamaha top three at the test.

The Austrian Grand Prix at the Red Bull Ring, renowned for hard b𒁃raking and acceleration, starts on Friday.
