Jorge Lorenzo wants to fight Valentino Rossi for MotoGP title again

Yamaha emerged as the dominant manufacturer in the 2015 season, with champion Lorenzo winning seven races and runner-up Rossi four from the 18 grands prix.

While Honda won the other seven races, only one came with its 2015 bike, with Marc Marquez and Dani Pedrosa reverting to the '14 frame after early-season struggles.

Rossi led the standings from the first round, but was overhauled by Lorenzo in the Valencia finale.

When asked if he fancied another battle with the Italian, Lorenzo said: "I hope, and we hope, because this would mean that our competitors are still behind.

"Hopefully it is like this again, because it would mean that Valentino or myself will become world champion again.

"In general the bike is very complete. Now the problem is that with the new regulations of electronics, and also the new brand of tyres, it changes so many things.

"Apart from the challenge, to keep the same more or less, if the electronics change and the tyres change, it changes so much of the feeling that you feel on the bike."

Lorenzo admitted a clearer picture would emerge following the first pre-season test in Valencia next week.

"It's difficult to know at this moment, because just made one practice, that was in Valencia after the race," he said.

"So we didn't check how the new electronics and tyres are working on other tracks.

"Especially also the factories have been improving their bikes and electronics in this time, from Valencia.

"Soon we will discover how all of the factories and all of the bikes and all of the riders are in this moment, in this new situation.

"At this moment I cannot tell you the performance of the riders, how it is going to change."
