ISO 8644:2006 Motorcycles — Light-alloy wheels — Test method

ISO 8644 specified methods for determining the performance of light-alloy road wheels for motorcycles under normal road use.

It is applicable to wheels for motorcycles with two or three wheels (including motorcycles equipped with side-cars) as defined in ISO 3833, of the following types: unit construction light-alloy wheels; andcomposite construction light-alloy wheels.


ISO 8644 Motorcycles Light-alloy wheels Test method, Radial load, bending moment, Torque bearing, radial impact test describes the general and performance requirements of light alloy wheel rim intended for use on two and three wheeled motor vehicles with or without side car.


1 General

1.1 Alloy rim should be produced in the design or technical document of production base.

1.2 Alloy rim surface should not have visual cracks, defects.

1.3 In alloy rim, it is required to mark diameter code and nominal width code of rim (reference to Annex F) at visual positions after tyre assembly.


2 ISO 8644 stipulated test for the wheels: 


Bending moment bearing capacity            

After the test of bending moment bearing capacity (as per Annex A), alloy rim surface is appeared cracks, visual deformations or any unusual unclutching at joints.

Radial load capacity

After the test of radial load capacity (as per Annex B), alloy rim surface is appeared cracks, visual deformations or any unusual unclutching at joints

Radial impact bearing capacity

After the test of radial impact bearing capacity (as per Annex C), alloy rim surface is appeared cracks, visual deformations or any unusual unclutching at joints or sudden air leak due to damaged rim.
