Motorcycle tyres and rims (code-designated series); part 3: rims

This technical specification establishes essential requirements for rims used in conjunction with motorcycle tires, specifically addressing a defined series of nominal sizes. The document focuses on the third part of a multi-part series dedicated to motorcycle tires and rims, detailing dimensional and geometric parameters necessary for compatibility and safety. It outlines specifications for rim construction, including width, diameter, and profile characteristics that ensure proper tire mounting and performance. The content covers various rim types suitable for different motorcycle applications, providing a standardized framework for manufacturers and regulatory bodies. By defining precise tolerances and measurement methods, the document facilitates interoperability between components from different producers. This approach promotes consistent quality across the industry while supporting the efficient design and production of motorcycle wheel systems. The guidelines serve as a reference for technical compliance without imposing specific testing protocols beyond those inherent to the dimensional definitions.
