MotoGP Qatar: Secret Ducati aero not for tyre cooling

Ducati’s controversial new aerodynamic units were judged to be legal by FIM stewards in Qatar yesterday but they aren’t being used for the purpose that is widely rumoured.

It was thought that Danilo Petrucci had been using the new devices, particularly the rear, to push air over the tyres to cool them down as he is a big man with an aggressive riding style.

The Italian has confirmed this is not what they’re for, but then went on to say he couldn’t tell anyone what their real purpose is, as he will get his pants pulled down.

“I can’t tell you because Gigi gets angry. We saw on television that they said it was to cool down the rear tyre, but in fact that is not the real reason,” said Petrucci, speaking at the track.

“There is also another part on the front. I asked what is its purpose, but unfortunately I cannot tell you as it is my contract.”

Team-mate Andrea Dovizioso didn’t use the devices during practice but had them attached for yesterday’s race which he won by fractions from Marc Marquez.

Suzuki, Honda, Aprilia and KTM yesterday all protested the devices but their case by chucked in the skip by officials. Yamaha did not join in, presumably because they used a similar thing last year to try and keep water off their rear Michelins.

The case has now been referred to the FIM Court of Appeal and a final decision should be made before Argentina.
