Marc Marquez' brother Alex has revealed the former world champion was livid with Honda after the 2023 RC213V showed no marked improvements at Valencia.
Marquez - who is still coming back from injury - was expecting some big changes to take into the winter but left Valencia 'angry' and uncommunicative.
"We were in the car together and we didn't say a word,” said Alex. “Marc was angry. I asked him if he had tried new things, he said yes, but that nothing worked, and that's it.
"I think that if Honda makes the steps forward it has to make, Marc will not leave.
"Because it's the team he's always raced with, that waited for him and respected him when he got injured. But if the bike is not the one for the world championship, then it will be possible."
