Early comments about the new Yamaha engine are positive but it's still down on power compared to Honda and Ducati. https://www.autosport.com/motogp/news/147371/yamaha-not-expecting-large-engine-gains
Morbidelli, who ended the test seventh overall, says the new motor is "more angry" in higher gears and was happier with it as the engine "keeps Yamaha's soul".
"I tried the new spec, I had a good feeling on it," Morbidelli told Autosport. "Seems a bit faster, a bit more angry in fifth and sixth gear, and this is what we wanted and this is positive.
"[It] still keeps Yamaha's soul, the engine has Yamaha's soul. It is really smooth. I am happy with the job they've done."
When pressed for what else he wants from the engine, he said: "What I would like is to have more power and keep the rideability that the bike and the engine has.
"I don't know if they will manage to do that, but it seems that this engine is already a step [forward]."
