Fabio Quartararo says Yamaha currently has no clear idea how to fix the problems with its MotoGP bike and return to competitiveness.
He explained that the new V4-powered M1 still has many issues, and the team is struggling to find the right direction for development.
Quartararo feels that despite ongoing testing and changes, there is no real progress, making it difficult to understand what improvements are actually working.
He also pointed out that constant experimentation with setups means the team cannot fully focus on performance or speed during tests.
Overall, he believes Yamaha is far behind its rivals and needs major improvements if it wants to become competitive again in MotoGP.
