I use the Givi Crash bar for 1,5 year and i had a few drops most of them stand still but also a serious one with passenger and overloaded. The protection was perfect. They certainly have a problem with corrosion on the welding points. I send photos to the local dealer and they send me...
I install the Givi crash bars and you don't have to remove them in order to remove the side panels. I also like them because they are not huge and provide excellent cover.
