The Yamaha Wall of Harmony

Yamaha team manager Daniele Romagnoli has decided that the wall that divides the Yamaha factory team is a good idea and that even Spanish rider Jorge Lorenzo will benefit from it.
The partition was placed in 2008 when Valentino Rossi switched over to Bridgestone tires while team mate Lorenzo was on Michelins and both tire manufacturers requested it to protect intellectual property and the swapping of key information.

With the introduction of the single tyre rule and with the entire grid will be running Bridgestone tires, and the wall is no longer necessity and should come down, however reigning World Champion Valentino Rossi has convinced the head honchos in Yamaha that the wall should stay up.
