Data Acquisition

Welcome to Data for Motorcycles’ data acquisition tutorial pages. Here you can browse our sections covering the various aspects of motorcycle data acquisition and how it is being used to understand more about how a motorcycle works. We are updating the site constantly, adding more detailed information about sensors, software, channels and how data analysis relates to chassis setup, rider input, and safety. Whether you have a data acquisition system or not, you can take advantage of the data we’ve collected over the past several years and learn how to improve your setup and riding skills.
