Yamaha has decided to suspend all on-track activity during the second day of the Sepang MotoGP test while it works to determine the cause of the issue that forced Fabio Quartararo to stop on Tuesday.
The Frenchman crashed at Turn 5 of the Malaysian circuit on the opening day of the official test and fractured the middle finger on his right hand. Despite the swelling and heavy bleeding, he returned to the track later in the afternoon, but his M1 stopped at Turn 2 due to an engine problem — specifically with the V4 power unit that Yamaha has focused its development on since last year.
