When I started to carry a passenger, my troubles began with my Industries 7 rack. I have Givi side cases and a V46 Monokey topcase. I previously posted the problem I had with the fender support arm coming into contact with projections on the rack, but I solved that with grinding a gusset and relocating a nut. Now the tube that supports the topcase and it's backrest pad has broken through at the attachment bolt slots. I could repair and strengthen this, but my wife has her eye on the BRP backrest and sport rack, which looks stronger. I have removed the portion of the rack that supports the topcase but retain the parts that support the side cases. Does any one know if these are compatible with the BRP setup? Also, would it be possible to switch over from backrest to topcase as occasion demanded? I don't mind a bit of modifying.
