Top quality, made from 304L stainless exclusively for Lambretta upgrades.I carefully measured with verniers on 3 different types of kickstart shaft (Italian s3, Italian s2 and Indian) before making them to make sure these would fit, with no slop but not too tight to get over the splines of the shaft and to make sure they covered the whole of the outer seal and on to the metal of the chaincase side, these should last a lifetime.
 
4 choices of thickness, this is the standard 1mm type.
