Ducati protest: 'Tyre cooler' legal, Dovizioso keeps victory

The MotoGP Court of Appeal has issued its verdict in favour of Ducati, declaring that the disputed part fitted to the machines of Andrea Dovizioso, Danilo Petrucci and Jack Miller during the Qatar season opener was legal.

Dovizioso is thus confirmed as the winner, with new factory team-mate Petrucci keeping his sixth place, while the device remains legal and can be used by Ducati in future races.

Pramac’s Miller failed to finish after a seat problem during the race, which saw Dovizioso hold off a final turn attack by Honda’s Marc Marquez to win by just 0.023s.

But the result was later thrown into jeopardy when the factory Aprilia, KTM, Honda and Suzuki teams protested the new device fitted to the swingarm, in front of the rear wheel, on the GP19 machines.

The FIM MotoGP Stewards Panel rejected the protest, unsurprising given that technical director Danny Aldridge had allowed the part, but the four manufacturers then lodged an appeal with the FIM Appeal Stewards, who referred the case to the MotoGP Court of Appeal.

The MotoGP Court of Appeal is made up of three judges belonging to the FIM International Commission of Judges.

At the heart of the issue was whether the device is designed to provide an ‘illegal’ aerodynamic effect (in this case downforce) – as the rival manufacturers claimed – or whether, as Ducati insist, its purpose is to cool the rear tyre.

Most probably it did both, causing the regulatory deadlock.

The protesting manufacturers – which had made their intentions clear to Ducati before the race, should the device be used – insisted they were not seeking to strip Dovizioso of victory, but wanted clarity from the technical rules.

“By filing this protest we are forcing them to evaluate, to judge, and to clarify the principles of the rules, the regulations, and the guidelines. This is the main purpose of our actions: to clarify what we can and cannot do,” said Suzuki team manager Davide Brivio.

Ultimately, the MotoGP Court of Appeal found in favour of Ducati by rejecting the appeal, confirming the provisional Qatar race results as final and the device under question can be used in future races.

But this may not be the end of the matter.

With Ducati Corse general manager Gigi Dall’Igna indignant at the decision to protest, rather than solve technical matters within the MSMA (manufacturers’ association), the Italian has suggested Ducati could file its own protest against the Honda fairing design.

The four manufacturers who appealed against Ducati can also take the matter to the Court of Arbitration of Sport (CAS) with five days of the decision.

The Ducati swingarm ‘tyre cooler’ seems to work in conjunction with a front wheel aero part, which presumably helps direct or optimise flow to the rear device.

By mounting the ‘cooler’ on the swingarm, Ducati avoided the MotoGP ‘Aero Body’ rules, which limit each rider to one fairing update during the season.

Round two takes place in Argentina this weekend (March 29-31).
