Taking tire rolling radius into account as the motorcycle leans can improve the accuracy of math channels that use that information. This post looks at how to calculate rolling radius, and use that in a wheel speed channel.

The post on histograms and suspension velocity analysis has been updated with an Excel file you can download; the file takes suspension velocity data, generates the histogram and outputs a summary of the percentage of time spent in each damping zone. The link to the file is at the bottom of the page here: http://www.datamc.org/2016/04/12/histograms-suspension-velocity-analysis/

One very useful technique for suspension setup is to use histograms and suspension velocity analysis to evaluate spring and damping settings. Histograms put values to how much time the suspension is active in each damping range (high-speed and low-speed compression and rebound damping), and by using some basic statistical analysis techniques, that information can be used to make spring and/or damping adjustments to the motorcycle and improve its performance.

"All About Geometry" from Sport Rider magazine covers front-end geometry (rake and trail), rear-end geometry (anti-squat) and center of gravity.
