Movistar Yamaha is the first MotoGP team to show the public a new fairing design to compensate for the banned aerodynamic winglets. On day 2 of the MotoGP Official Test 2017 at Sepang, Valentino Rossi tested his M1 fitted with concealed winglets.
Rossi's team-mate Maverick Vinales also tested the new fairing. With this concealed winglets, the M1's fairing is now wider and larger. According to the new rules, which only ban wings that are "protruding from the fairing or bodywork and not integrated into the body streamlining."
Except for Yamaha, all the other manufacturer are testing their machines with normal fairing at Sepang, but on day 3, we can expect some of them to come up with a specially designed fairing to retain some downforce generated by the winglets, which were banned at the end 2016.
Yamaha's Massimo Meregalli said, "I can not give any information about what we are testing, but what we do are checks and comparisons, so we want to have information from the two riders."
When asked about the new fairing design, Rossi replied, "They tell me I cannot speak about the new fairing! But sincerely speaking, first of all, it is very beautiful! I like.
"It doesn't make a lot of difference, but it is more beautiful. So we will continue to use and try tomorrow. Then we will see."
In 2016, Ducati was the first manufacturer to introduce and start the winglet battle in the paddock. The Italian marque also found success with the winglets to generate more downforce which gave them two victories last season.
Ducati team also tested a slightly updated fairing which had some vents on the side. We can expect the team to bring new fairing to provide more downforce before the season opener at Qatar.
