BS ISO 9129:2008 PDF

1   Scope This International Standard specifies a measuring method for determining the moments of inertia of the motorcycle and of the motorcycle/rider combination. It applies to two-wheeled motorcycles. Other measuring methods can be used if it is demonstrated that the results are equivalent. Measurement results obtained exclusively by the method described in this International Standard (see Annex A) cannot be used for an evaluation of vehicle stability because they deal with only one aspect of this very complex phenomenon.
