This is for a set of 3 washers especially for the Lambretta chaincase side.
Made with a zinc plated steel outer ring and an inner viton rubber seal that is raised on the inside, these make a perfect seal against the chaincase side.
I have been looking for these for around a year and finally found some: Result - INSTANT SUCCESS!!! No more leaking ST90 all over your drive and garage! I have been using these since 2005 and wouldn't ever go back to those ill fitting mineral washers!
