Ecstar Suzuki's Joan Mir bagged third place on the opening day of MotoGP testing at Jerez but isn't focusing on the top speed of his 2020 engine.

Mir set a 1'38.012 which compares favourably with fastest man Maverick Vinales' best of 1'37.131 given Fabio Quartararo in second was aos three-quarters of a second down.

But the young Spaniard believes that although the new engine is quick in terms of top end, it is not it's best point.

“On the top speed, I don’t know if it’s faster or not, it’s not the strongest point of our engine. But it looks like the smoothness and the grip is quite positive," said Mir, speaking at the track.

"So we have to continue working, I don’t think we arrived in the maximum level of the engine. So we have to continue working to reach that level.

“It looks positive because we tried again the old engine and the new engine, we compared them a little bit, and we confirmed that the new engine is a bit better.

“We tried some things of the chassis, some things to make the chassis more rigid, more stiff. And for some parts it was a bit better for the brakes and some other things, but then for turning it was a bit worse.

“We have to make the balance and see if for one track it’s maybe OK, but not for another one. It was not the most positive thing to try today, but I’m happy.”
