From my understanding Shindy makes the factory Honda rebuild kits & ships them to Honda so they can put their label on them. I've rebuilt both masters & all 3 calipers on both my R's with Shindy kits & have no complaints plus there much cheaper than the rebranded Honda kits. Also if you have an 86 front MC you can get the Shindy kit for the 87-89 front MC & it will work.
