More secrets at Fiat Yamaha in 2010

The controversial issue of data sharing between Valentino Rossi and Jorge Lorenzo has taken another twist after Yamaha bosses insisted there will be less sharing of information between the pair next season.

Previously, fierce rivals Rossi and Lorenzo have insisted that their Yamaha YZR-M1 data is open for each other to check.

But that free policy appears to have vanished in 2010, with Rossi’s team boss Davide Brivio declaring: “In 2010 we will have small changes in this sense, compared to 2009 when the challenge was completely open during the weekend and during the practice.

“In consideration of the fact that the two riders are the main rivals for the championship, we have decided to respect this competition internally and to respect their own ways to race and to approach the competition, so during the weekend the two teams will be much more independent and the challenge will be closer.

“Not much information can be exchanged between the two teams.

“At YMC level, back at the office, the engineers can compare the data and the information, but the two teams inside the garage can work more independently from a technical point of view.”

It has been rumoured that Rossi has become increasingly agitated at Yamaha’s policy of allowing Lorenzo and his crew access to his data.
