MotoGP champion Jorge Lorenzo was left lamenting "very strange feelings" with his bike after the opening day of testing at Phillip Island.
While the Yamaha rider dominated the three days of testing at Sepang two weeks ago, the Spaniard finished down in 16th position today, in a session marked by the mixed weather conditions.
Lorenzo completed hardly any running on slicks and was over eight seconds off the pace.
"A very unlucky day," Lorenzo told reporters at the end of the day.
"Mixed conditions and not really completely wet and not good enough conditions for the dry tyres.
"So in the end only two laps with the slicks, and very strange feelings.
"I'm looking forward to seeing how the bikes works with the Michelins on a full day tomorrow," the world champion added.
The three-time MotoGP champion also admitted the standard electronics still needed a lot of work in order for riders to feel comfortable when running in wet conditions.
"It's not easy," he said. "You have to be quite careful with the throttle and quite smooth to stay on the bike, but little by little we are going to improve it."
