Jack Miller feels he was able to “clear” the vibration issues that thwarted him over Aragon Motogue’s weekend in the post-race Motorland Test.
Miller was 14th in the Aragon Grand Prix suffering from rear vibration issues, but the Pramac Yamaha rider feels he was able to “deepen” the question after a day later post-race test.
“After being disappointed with the vibration early in the race, it was good to test it and clear it,” Jack Miller said after the post-race Aragon MotoGP test.
“We were able to look into the test items and diagnose the small issues we had, and we got a deeper understanding of the problems.”
Miller added that the items he tested are taking Yamaha “the right way.”
“It was good to test some of the items,” he said.
“We are going the right way.
“After taking a break, I went back to my bike in Barcelona (this week). It’s a good place to test because we’re struggling with long corners.”
Jack Miller details Yamaha test results
Miller detailed some of the new items he tested, saying, “There’s no chassis, but almost everything else. SwingArm – I used another one over the weekend and then back-checked to make plans for the future.
“Electronics – we are trying to understand better strategies and develop better strategies. We have some updates from Japan.
“Aero is the same. I saw Fabio run the latest Aero.
“We had these options over the weekend, but we chose not to run during the race. We simply tried it out, so we didn’t do any damage during the race weekend.”
Specifically, on aerodynamics, he added: “I was pretty pleased with it. It helped with the turning. It made the bike even more agile.”
Miller admitted that there was “no much difference” in the new engine compared to what he had been running since the new engine, which was also tested by Augusto Fernandez over the Aragon Grand Prix weekend.
He added that what was tested in Aragon was “a little step in the same direction.”
Looking forward to the private Yamaha test in Barcelona, Miller explained that it is important for the Iwata plant to test in such a location due to the low truck grip.
“Same in terms of bad grip,” Miller said, comparing Barcelona Catalña to Motorland Aragon.
“These two (tracks) are pretty close, these are the tracks we struggle with.
“In Argentina, we struggle even more when there is no grip in the rear.
“So it’s going to be a useful test to help you understand how to make your bike work.”
