Lorenzo and Rossi to make chassis decisions

Lorenzo and Rossi to make chassis decisions

Jorge Lorenzo and Valentino Rossi dedicated their single day of post-race Jerez testing to chassis comparison. The Yamaha Factory Racing duo are aiming to fine-tune one general chassis as opposed to swapping between frames on race weekends.

In Spain over the weekend, observed that Lorenzo was fitting the same set of tyres to each of his available frames in order to make back-to-back comparisons. Bearing in mind that both riders stressed after Sunday’s race that bike improvements need to be made, Team Director Massimo Meregalli points out that fine-tuning a single chassis will be paramount in order to make proper progress.

"We have been comparing two different 2013 frames," Meregalli explained during a video interview on Monday. "The differences are pretty close and so far we have not identified which one is better. You can’t see much because the frames are identical; obviously something inside them is different, but I am not in the position to say because I really don’t know. You would have to ask the Japanese (engineers)!

"The riders are always looking for more performance. Development is always going on, especially with electronics. For sure we learned something from the race and we will try to apply what we have learned as soon as possible."

With Yamaha having won of the opening trio of races this season, Meregalli went on to conclude that Lorenzo and Rossi will soon make a call over chassis:

"For us, it is just better to know which one (is better). We would like to have a base setup based fixed on only one chassis, to avoid having the possibility of changing the frame during race weekends. The difference are small, so we have to identify them. One chassis is better in one point, the other one in another area. It is a decision each rider will take - I’m expecting by the end of (Monday) - but that really is not a ‘must’.

Following the Gran Premio bwin de España, reigning world champion Lorenzo sits third in the championship and four points off the lead, with Rossi a further 14 behind.
