washer

A lock washer is a small, flat ring that you place under a bolt or nut to distribute the load over a larger surface area and prevent loosening due to vibrations. On scooters and mopeds, lock washers are used in numerous places, from wheel mounts to brake calipers and subframes.

When choosing the right washer, pay attention to the inner diameter, outer diameter, and thickness, as these must fit the bolt and the part you are working on exactly. On this page, you will find washers for specific Piaggio and Peugeot models, as well as universal sets for common bolt sizes.
