Michelin’s MotoGP chief Piero Taramasso says Jorge Martin's crash at the start of the Sepang test was due to a 15C drop in the inside temperature of the rear tyre.
On the opening day of pre-season testing in Malaysia, reigning MotoGP champion Martin was thrown off his Aprilia at Turn 2 as he began an early flying lap of his third run. Crashing to the ground head first, the Spaniard broke his right hand and left foot and had to be transported to a nearby hospital.
