Gobert and the boys have a chuckle over the computer-generated graphs. Boehm looks on with concealed horror, ego crushed. For this exercise, we used but a portion of Yamaha's extensive data-acquisition hardware to help pinpoint where Gobert is fast (and Boehm is not). Data acquisition uses a small, bike-mounted computer that receives inputs from various sensors, including wheel speed (front and rear), engine speed, throttle position and suspension movement; during racebike development, teams use many additional sensors. The data are downloaded to a trackside laptop or radioed to Uranus.
