Scope

This International Standard specifies the dimensions and mechanical properties of roller and
bush chains together with details of associated chain sprockets (see Annex A), in the range 6.35
mm to 19.05 mm pitch, for use in motorcycle applications. These chains are suitable for external
drives (e.g., rear drives).
It covers dimensions, tolerances, length measurement, preloading, minimum tensile strength
and minimum dynamic strength.
