0801.38.630 (080138630) - 25/9 ratio speedometer drive for all bevel drives with Nippon Denso gauges [Darmah etc].
This is a decently manufactured reproduction unit made in Germany. You might need to lubricate the internals with a thick oil (via the spring loaded ball on top) before you use it.
Order it by itself or also get a new stainless steel washer that goes between the inside of your fork leg and the speedo drive.
*NOTE: The long tab will fit ALL wheel applications on bevel drive twins but you might need to trim the length of the tab so that it doesn't bottom out inside your specific wheel..
