Valentino Rossi Talks About The Yamaha YZR-M1 From 2004 - 2009
At the end of every year, Yamaha hold a presentation to talk about their YZR-M1 MotoGP bike and how they changed it for the new year. In it, Masao Furusawa and Masahiko Nakajima give an always fascinating and surprisingly detailed technical presentation on the bike and the important factors they improved from last year.
This year was slightly different: As Masao Furusawa will be retiring at the end of this season, Yamaha gave a presentation covering all of the bikes he has worked on, from the 2004 machine through to the 2010 M1. Furusawa gave a presentation covering the bikes from 2004 through to 2009, and his descriptions were illustrated by a video featuring Valentino Rossi, talking about each bike and each season in detail, the strengths and weaknesses of the bikes. Yamaha was kind enough to release that video for use to the media, and allow us to post it to the internet. It's shown below:
