Top view of the left site. In this photo the helmet lock has not yet been mounted. Since then, I've mounted the helmet lock. It's great! This is a perfect position for the helmet lock. I use a mountain bike seat retainer cable ($5 from my local Performance Bike Shop) to go through my full coverage helmet, and I can use the same cable to lock my riding pants and/or riding jacket. Yes, the pants and jacket fit into the Givi E21 Monokey saddle bags, but then I can't haul other crap.
