Footrests and their associated fittings, side-stand etc are prone to wear, corrosion and physical damage. Renewing these components is an easier option than trying to restore them. Anodized aluminium is notoriously difficult to sort out. Rusty bolts and nuts likewise.
So, if you decide to take the easier route of replacement rather than refurbishment, then this part and perhaps some of those listed below maybe required:
Add as many items as you wish to the same shopping cart new Footrest rubbers 2GH2741300, crown nut 9530308800 and screws 9015705079 for example, and still only pay the same single fixed price shipping cost.
This component may have other applications in the Yamaha model range so please ensure the part-numbers you order are correct for your particular model.
