Fastener Dimensions

The following fastener dimensions have been measured from a 2006 GS500E, so may not be appropriate for all other models.

Where speciality components are found, such as shouldered washers, the closest conventional replacements have been listed instead.

This page is a work in progress and will periodically be updated.
