Whatever type of Honda you run, if any of the anti vibration mounting rubbers fails, it can lead to hair line cracks of the metal or plastic part of whatever they are supposed be protecting, in this case the mudguard. These are inexpensive consumable items that if renewed regularly will ensure no expensive replacements or repairs will be required on the mudguard fabrication itself. To ensure you are aware of where all the anti vibration mounting rubbers are on your machine, try browsing our online 'parts list' fiche where applicable, or our online catalogue?
