I could count on 1 hand the amount of time I used those helmet locks on the back. I have a small cable lock I use. I put the helmet on the backrest and just run the cable through the helmet buckle and on the luggage rack. Those locks are more of a pain in the ass than what their worth. If you have saddle bags mounted they still get in the way.
