Jorge Lorenzo sജigned off from Valencia with the fourth fastest lap time on the final day of of♑ficial 2017 MotoGP testing.

The factory Ducati rider's main task,𝕴 alongside team-mate Andrea Dovizioso, was to evaluate a 'semi-new' bike, understood to in♋volve some new chassis parts fitted to the present GP17.

"Today we tried again the semi-new bi♒ke. For the moment it doesn't work better than the curr🎉ent 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 w🧜ish is to make the next Desmosedici more effective in mid-corner.

"We need the bike to turn better to be faster in the m⭕iddle 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 compromise on top speed if it helped cornering.

"I already did with the new fairinᩚᩚᩚᩚᩚᩚ⁤⁤⁤⁤ᩚ⁤⁤⁤⁤ᩚ⁤⁤⁤⁤ᩚ𒀱ᩚᩚᩚg," he said. "So I am one of the riders who believes that you make more of the time in the corners than in the straights."

But the Spaniard emphasised that the bike doesn’t need major changes, given the success of his te𓄧am-mate this s🌺eason.

"To be honest, Dovi got a lot out of the bike. He knows the bike 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 in𓆉 some races the management of the tyres was good, he was very good at that, and this al💦so helped him to win some races.

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

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