Marc Marquez/Valentino Rossi Sepang MotoGP clash data stays secret

At the height of the row between Rossi and Marquez, Honda declared its data would prove precisely what happened in the Malaysian Grand Prix collision at the centre of the furore.

There had been debate over whether Rossi kicked out at Marquez as they came together.

Honda ultimately declined to share the data publicly at the Valencia season finale after a request from the FIM.

The organisation's president Vito Ippolito says the FIM and Honda have now made a joint decision to keep the information private.

"It is true that at the end of the season the polemics around the Rossi/Marquez case swelled to unprecedented levels," he said.

"For that reason, we asked all the people involved, including the teams, to refrain from engaging in controversy about what happened in Sepang.

"During the last competition in Valencia, team Honda informed us that they had all the telemetry relating to the incident.

"Now the data is in our hands, and Honda and the FIM have decided together not to release it so as not to fuel further polemics."

He stood by the FIM and commercial body Dorna's handling of the 2015 row.

"There have been difficult moments, and I would say that it is inherent to the sport," said Ippolito.

"The most important thing is to manage to find the right response to such situations or at least to limit the damage and make adjustments.

"I would say the same about the end of the MotoGP season, which was a fantastic saga and also a dramatic one.

"The dispute was brought before the CAS [Court of Arbitration for Sport] and the case is now closed."

During the controversy, Ippolito issued a statement arguing the rows were "poisoning" MotoGP.

The pre-race press conference at Valencia was then cancelled in favour of an extraordinary meeting between riders and series chiefs, although the key protagonists still held their own individual media briefings afterwards.

At Yamaha's 2016 season launch this week, team boss Lin Jarvis intimated that talks between Dorna, the FIM and teams over what changes should be made in the wake of last year's row were ongoing.
