Since Harley does not put helmet locks on their bikes, my wife and I wanted a place to secure our brain buckets. We ride into a busy city often to eat out or visit friends and we hate to carry the helmets with us. This lock comes in very handy when we leave the bike and keep our helmets on the machine. It can be placed in several locations; we chose the right handle bar on our mini ape hangers.
I am rating this prior to installation. But looks like it's so simple a caveman could do it. Worried about marring the paint and casting about for something to put between the lock and the paint first. I am sure it is very secure and the two keys work perfectly. Glad I ordered it as I am tired of carrying that dang helmet with me everywhere I go!
I always ride with a helmet. A deer strike a few years back resulting in a helmet with severe road rash reinforced my thinking. Now no need to carry my expensive replacement helmet around or worry about having left it perched on the mirror.
