Ducati brought a raft of new parts of the Jerez MotoGP round and Jorge Lorenzo has already seen the benefits, saying they are taking the GP18 in the direction it needs to go.
The Spaniard managed to keep pace with team-mate Andrea Dovizioso in second practice although they are using different fairings - Dovi has not yet attached the jug-eared aero package to his GP18 and hasn't tried the new parts.
"We are trying new things in the bike, Ducati brings here some new parts of the bike. They work well today, to make the bike more smooth with the throttle, in the middle of the corner and the acceleration," said Lorenzo, speaking at the track.
"And this a little bit goes into direction that I want for that bike, that we lose a little bit with the new bike but improved in some areas, in stability, in smoothness, in exit of the corners.
"With these new pieces the bike goes a little bit in the direction I want, so that's why today this give me a little bit of happiness."
