I saw some people talking down on SHAD, but they had the size I wanted for my last tour so i bought one. I had to fabricate my GIVI 357 a tad to fit both GIVI and SHAD top plates, but that was relatively easy. I hit one road in southern NY south of the Cascades that was the worst washboarding I’ve seen since i lived in VT. It was relentless for 5+ miles. That night at the motel i noticed my top plate was a little loose, but that’s because it was mounted with my fabricated setup and needed a tighten. As for the SHAD in the plate? It stayed rock solid. Passed my test🤷🏻♂️
