I bought these washers to use on the drain plug on a Honda Metropolitan scooter for £50. My scooter is from 2008. It was a good direct replacement for the shredder and we are almost the same size just a little thicker. Check out my photos of these new shims versus the stock Honda shims. They fit very well on the drain plug and leave no room around the drain plug inside or outside - see photo of them on the drain plug - I fitted them.
