Morbidelli enjoyed a positive day, which he ended with a quickest lap of 1min 39.014secs that put him second on the timesheets after eight hours of action. The PETRONAS Yamaha SRT rider focused his work on electronics from early in the morning, with the aim of finding an explanation for the race pace and performance challenge he faced in Sunday's race. The Italian, who completed a total of 78 laps of the Catalan track, also tested a new rear tyre.
Fresh from his first premier class podium, Quartararo continued his quest for further improvement from the performance of his bike. The Frenchman had his first outing on track after noon, and devoted much of the test to electronic settings and strategies. Over the course of 56 laps, he also tried out several different tyre compounds, and finished the day as the fifth fastest rider with a time of 1min 39.428secs.
The MotoGP riders will return to action from June 28th-30th at the Dutch GP.
