We all have reasons or preferences for justifying our purchases. Some people like capacity, or color, or shape or price when making decisions. All perfectly acceptable reasons imo. I bought my Givi 47 specifically because of Redfish's rear view posted pic in post 3 which I discovered back in June of last year when making accessory decisions. The size looked right to me, the shaped (more angular than round) seemed to match the angularity of the FJR's bags better than the more rounded Givi's, and the light panels matched the clear light panels of the FJR's taillight on my 2018A. A cohesive look IMO. The Givi is a much more expensive trunk than the one I had on my Honda ST 1300 for 11 years which cost $79 incl mounting plate and functioned perfectly for all 11 years and over 100,000 miles that I owned it. It was rounded and matched the more rounded shapes on the ST better imo. So although not as expensive as a Yamaha top case, the Givi was still a rather large expenditure in my mind. I also went with the SR 357 mount so highly recommended here on the forum. No issues installing mine at all, went right on. So far 11 months and 14,000 miles in, I am very happy with my choice. The Givi case holds more than I will put in it. It has functioned perfectly, easy on easy off, easy opening, easy closing, looks good to me. No issues at all.
We all like to think we have it figured out and made just the right purchases and that if everyone else would just buy what we have and they will be perfectly happy. But if that were the case we'd all be riding the same bike, same color, same windshield, same seat, same bar risers, same crash bars, same trunk, same helmets, same jackets, same gloves, same boots... basically clones just in different sizes. But that is not the case, and never will be with multiple people with different wants, needs desires and preferences. Listen to what others recommend, figure out what it is you like/prefer and buy it...and be happy with your decision. If you are not happy in the end, sell it and buy something else. So far, I'm happy.
