AXIO bag is a few years old.Was on my Hypermotard and now the Hyperstrada. Can't remember where I got it but I had 2,this matt black one (bought new) and another metallic silver one I sold recently (that one was from ebay)
The horn is plug and play as far as the connections are concerned,plenty of length on existing cables,however mounting was a *****. I wanted it mounted as close to the bike as possible to hide it from obvious view so had quite a few attempts and finally got it sorted. (2 days of buggering about). Bought a steel 3 x 4 flat L bracket from OSH (actually bought several) and after much trial and error managed to get the correct length to secure it to the existing horn mount and then cut the bottom of the L to the right length to mount the horn and still access the beak mounting screws.Then had to bend the bracket slightly to get the correct clearance/angles and finally the rubber washers to allow the horn to vibrate correctly to allow the sound. Its much louder than stock and a better sound. I had these on all my prior bikes and definately get noticed when its tooted (the stocker is embarrasing on a bike like this (IMO). Cant get pictures as its so well hidden - sorry
