Movistar Yamaha riders Valentino Rossi and Jorge Lorenzo remain undecided for now over whether or not the winglets used on their M1 machines for the first time during a race weekend at Misano offer much of an advantage.

Neither rider opted to run the wings on the front fairings of their machines during qualifying, although both did briefly experiment with the modification in practice.

Lorenzo, who set a new pole record at the Marco Simoncelli Circuit, said: "I tried them in practice but we didn't feel so much difference and I think that we still have to try at more tracks and more
locations because we cannot say clearly what is going on with these wings.

"But also in the future it is important to investigate more, also with these wings but maybe also with another type of wings and it could be interesting to see if it really works," he added.

"But it will be not like in Formula 1 where almost everything is aerodynamic."

Rossi - who didn't try the development on Friday and only did a short run with them on Saturday - was equally unimpressed, saying in reality any difference created by the winglets was negligible.

"With the wings I don't feel much difference. Sometimes I think I feel something, a little bit more contact in the front, but the reality is a small difference," he said.

"It is unbelievable how much people speak about the wings, so it is interesting but this is a small, small modify but you can do a lot more things on the bike to make more difference than the wings."

Ducati has also featured winglets on its GP15 machines this season, which were used by the Italian factory for the first time on Casey Stoner and Nicky Hayden's machines in 2010.

Or (oh boy! got me thinking now!) the wing could be part of the fairing, the same shape as the fairing when neutrally positioned, that angles down under hard acceleration, thus creating its own scoop.

EDIT Angles down simply because the top of the wing moves back in to the fairing.

Suppose they could be built into a scoop so they don't stick out.

Surprised nobody had looked into motorising them so their angle of attack varies with the bike's activity eg point down under hard acceleration (to push front down), neutral the rest of the time ( to prevent understeer) etc.
