Jorge Lorenzo signed off fr🅺om Valencia with the fourth fastest lap time on the final day of official 2017 MotoGP testing.

T🌱he factory Ducati rider's main task, alongside team-mate Andrea Dovizioso, was to evaluate a 'semi-new' bi🥀ke, understood to involve some new chassis parts fitted to the present GP17.

"Today we ꦍtried again the semi-new bike. For the moment it doesn't work better than the current one," Lorenzo declared. "And many little things, the same things as yesterday, to be really sure of the way the engineers must follow for the new bike."

Like title runner-up Dovizioso, Lorenzo's main wisಌh is to make the next Desmo♍sedici more effective in mid-corner.

"We need the bike to turn better to be faster 🐈in the middle of the corner, in general terms. And also, if the engine can be a little bit more progressive, more docile, more smooth, it will also be fine."

The triple MotoGP champion, who finished his first Ducati season with seventh place in the world championship, confirmed that he would be willing to comp༒romise on toജp speed if it helped cornering.

"I already did with the new fairing," he said. "So I am one of ✱the riders who believes that you make more of the time in the c🅷orners than in the straights."

But the Spaniard emphasised that the bike doesn’t need major changes, given the success o♚f his team-mate this season.

"To be honest, Dovi got a lot out of the bike. He knows the bikꦉe for five years, and he made an unbelievable championship, it looks like he understands the bike and he can get the maximum.

"Also it's true that he was very fast, but maybe in some races th🌸e management of the tyres was good, he was v💜ery good at that, and this also helped him to win some races.

"Maybe in just pure speed we will need some tenths, especially in 𓆏the middle of the corners to really try to win races, a lot of races in a c𝓰onstant way."

Ducati will take part ౠin a further private test at Jerez next week before deciding on the final design for the GP18.
