I've had my cruiser for about 4 months and so far I love it with the exception of the horn. I think for such a large vehicle that the horn does not do it justice. So, my friend and I installed the "Big Horn" air horns from Pep Boys (cost ~$30 USD) and man what a difference. They are very loud and when someone is trying to cut you off and you blast those bad boys they get the heck out of the way. I used the existing horn wires so installation was very easy. The benefits so far are enourmous, already I had a lady almost run into me and when I blasted the horns she quickly moved out of my lane. I think this is a minor but very essential mod that perhaps no one has considered but should. Cost and installation is cheap and it includes just about everything you need.
