Got the hook. Works great! I've got an expensive helmet now. In in the past I've dropped or knocked helmets off of various spots I've put them on the bike... the seat, the mirror, etc. Vstroms don't even have an actual helmet lock like most dirt bikes do, so this thing is handy. Great idea for the price. Some day I hope he comes up with a locking version.
Took a couple minutes to install. Vstrom riders need to remember not to remove the screw at the end of the bar weights, just loosen it (you probably have a 1/4" you can loosen it without any problem) then just pull it out by wiggling it a bit. If you remove the screw you will lose parts inside in your handlebar!
