Reigning MotoGP World Champion Marc Marquez is unhappy with the changes Honda made to his RC213V for the Valencia test and says they must find a compromise between the 2014 and 2015 chassis before the Valencia test.

Marquez spent all of yesterday using the 2015 prototype, which has revised engine and frame, but went out on the 2014 bikes in his last exit and immediately set the quickest time of the three days.

“At the moment, the character of the engine I don’t like is the way of the engine brake. It was locking a lot so we must go on the other side. On the exit of the corner it looks a little bit too aggressive but we can manage that with electronics,” said Marquez, speaking at Valencia.

“The problem is the chassis is a real part I didn’t like. I was not able to make the best line on the corner and when you are not on the best line from mid-corner to exit you aren’t on the correct speed and everything coming worse.

“In one day, is difficult to say. The positive is where I was struggling more on the last part with the brakes we improve but then they try another thing in the chassis on the rear, on that part I don’t like. We need to make a compromise between chassis to improve.

“We can try many things, geometries, we didn’t play with the setup, but I am happy because they understand well what I need. I set my best lap on the current bike after spending all day on the new prototype.

“The biggest difference here was the engine, but that affect that chassis directly. Brno is totally different and there it was working well but here the rear part I didn’t like it. We must find the best compromise for Malaysia test.”
