The big performance difference between new and old tires, along with unsettled weather, makes it challenging to compare his times directly to his M1 performance during grand prix weekends.
During the recent Catalan MotoGP, Quartararo set impressive lap times, including a 1m 37.8s in qualifying and a Sprint best lap of 1m 38.9s, showcasing his high potential.
Yamaha and Honda were the only manufacturers present at the test, with Quartararo outpacing the competition, leaving fellow riders like Johann Zarco behind.
Quartararo aims to bridge the gap to his current bike at the upcoming Misano MotoGP test, showing a strong determination to continue improving and pushing for better lap times.
