Mopeds — Measurement method for moments of inertia

ISO 9043:2008 specifies a measuring method for determining the moments of inertia of the moped and of the moped/rider combination. It applies to two-wheeled mopeds. Other measuring methods can be used if it is demonstrated that the results are equivalent. Measurement results obtained exclusively by the method described in ISO 9043:2008 cannot be used for an evaluation of vehicle stability because they deal with only one aspect of this very complex phenomenon.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
