Yamaha: Rossi will remain important for 2021 development

After 15 seasons together, Rossi’s time at the factory Yamaha squad came to an end at the conclusion of the 2020 campaign, with the nine-time world champion remaining a factory-contracted rider with Petronas next year on current-spec machinery.

Though Jarvis admits Fabio Quartararo and Maverick Vinales will lead some of the development at the factory squad, but doesn’t believe Rossi “moving next door” will change his role much from what it has been previously at Yamaha.

“He’s done 15 seasons with the Yamaha factory team. That’s quite extraordinary,” Jarvis said of Rossi’s time with Yamaha.

“He did it in two stints, first seven years [from 2004-2010] before he took a two-year break [to join Ducati from 2011-2012] and then eight years when he came back [in 2013]. 

“So, it will be a change, there’s no doubt because moving next door as such will be different. But on the other side, it will not be different because Valentino will get full factory support next year.

“He’ll be riding a factory bike with the same spec as the factory riders. It is true that some of the development will be led more by the factory team, but Valentino is a very important part of our data gathering. 

“Having more riders on the track is important and there’s no question our engineers will be looking at the data of Fabio, Maverick and Valentino to develop and further progress the factory bike. 

“But also, we get some interesting information as well from having Franky [Morbidelli] out there [on the older bike].

“So, I think that it will be not a huge change, it will not be a deficit in any case ,and it will not change very much how we develop the bike.”
