The configuration of mounting holes on the wheel hub of the Yamaha YFZ450, specifying their diameter and arrangement, is a critical measurement. This specification determines compatibility between the vehicle’s hubs and aftermarket wheels or spacers. The specification is usually expressed with two numbers. For example, ‘4/115’ indicates four mounting holes positioned on a circle with a diameter of 115mm. The correct specification must be verified when sourcing replacement parts.
Adherence to the correct specification is paramount for safe and effective wheel mounting. Incorrect specifications can lead to wheel instability, damage to the hub, and potential failure, jeopardizing rider safety. Understanding this specification facilitates customization and maintenance, enabling owners to enhance performance and aesthetics through appropriate aftermarket options. Historically, standardization of such measurements has been driven by industry needs for interchangeability and user safety.
