Once again, there was no clear agreement on the value of aerodynamics, with team-mates making different choices, and only both factory Ducati riders running without any wings in both sessions.
That in itself was unusual: hitherto while Dovizioso is no great fan Lorenzo has used the box-kite bolt-ons much more often than not.
At Honda, Marquez used the side-ducted bodywork, while Pedrosa did not (nor did Crutchlow).
Suzuki’s Alex Rins used the aero fairing, team-mate Iannone did not. At Pramac Ducati, Miller had the aeros on, Petrucci not.
