Yamaha bosses happy with MotoGP reliability if not power for 2021

Yamaha MotoGP chief Lin Jarvis is confident that Yamaha's reliability issues are now fixed but the lack of horsepower will have to wait until 2022 due to the engine development freeze.

The Iwata factory illegally changed its valves at the Jerez round this year which brought about engine blow-ups but as soon as they were put back to stock, the problems halted.

“For the 2021 season, we’re quite confident in our engines because of the reliability that we’ve seen using the right valves this season,” said Jarvis. “The regulations mean that we will continue to use those engines next year.


“We’re always missing horsepower, so we could do with some more. But we’re going to have to wait till ’22 to get that when we’re able to redevelop or use our development on the new engines.

“We actually did change our engine department organisation at the very beginning of this year. So, I don’t really expect any major changes in the future, not in the near-term. But I think the error that we made this year was made before the beginning of this year.

“I think in terms of the pure engine department, our engines, honestly speaking – apart from the weakness in one valve batch that we had – have been very reliable for the rest of the season. Some of our engines have done 3000km, which is pretty extraordinary. We had to do that because we had to park a load of engines.

“I think the main attention for the future improvements we will make is a much more rigid attention to detail in how we prepare for the season, reconfirming quality of components, reconfirming on the regulations. So, a lot more reconfirmation will be required.”
