So this summer I hope to get Megan on the back of the motorcycle and do some trips. Part of this involves here getting some gear, but it also has involved her having some sort of "backrest" for the back of the bike to lean against. My bike doesn't have a ton of options for this, but after doing quite a bit of research this winter I opted to go with the Givi system. It was cheaper than the BMW system (and the case looks better) and it didn't involve me purchasing an entire new seat for the bike.
After getting the rear rack on the bike, I am not thrilled with how it looks, but it looks fine. It just detracts from the minimalism that I like on the bike. The Givi gear seems to be really well built. I just feel that the top plate they have is a bit thick and it unfortunately does not have any utility for strapping gear down when the case isn't on the bike. I may look into trying to fabricate a replacement aluminum plate which could be thinner, but we will see. Again, it doesn't look horrible.
I can't deny the utility of the top case though. I used it riding to work last week and the 47l case can hold quite a lot.
