MotoGP video: The radical changes Honda and Yamaha are having to make

Once MotoGP's two dominant manufacturers, Yamaha and Honda are having a really bad season on track - but are putting building blocks into place to avoid more seasons like that in the future.

Honda, meanwhile, has headhunted the designer behind Aprilia's MotoGP transformation.

But how much of an impact will either of those things have, and which of the two is closer to winning again? Simon Patterson and Valentin Khorounzhiy delve into that in the latest video from our new MotoGP YouTube channel.
