I've owned several GIVI mounting plates. All of them have worked perfectly. I ended up getting the wrong year plate mounting hardware. I just purchased replacement hardware from Home Depot. So, double check your product model number when ordering. In this case it was an error on GIVI's part.
Using it on a OEM Honda ST1300 Tail Trunk. Stiff little rack , found that out trying to get all 4 mounts to hit a flat table evenly , one was off 1/8" . Wish the silver finish was more durable chrome. I reinforced the bolt holes with epoxied sheet metal inside to prevent top lid cracks. Otherwise it should work fine. ( I'm picky ; retired product designer )
I needed a set of spacious side cases for my V-Strom for longer trips. The E360's was an exact fit for the Givi racks on my bike. I've not used them on a trip yet but they allow me to take "to much" on my upcoming 8 day trip. LOL. They are well built and should serve me well. The only downside is, they are keyed differently, but I can deal with that.
First time I strapped bag to bike it ripped at contact point over 1 inch. Now it's not water proof. When I got back from trip, forgot to mail it back. Got around to it 2 years 3 months later. Opps. 3 months too late. I mailed it to Givi asking for repair or replace, they mailed it back to me unrepaired. Spit in my face. Sorry. Your 2 years is up. Do you want to do business with a 2 year warranty company? Not me. Givi did not do the right thing in this instance.
