Not sure how this would work for the KLR, nut it is posted on another of my forums and is a neat trick, I have this on a couple of my bikes.
From my other board said:Go to a bike store and get a bottle bracket holder.... and buy a phone clip.
separate the clip...
Drill a hole on the top of the clip...
attach the clip with the screw provided with the bracket..
install on Rebel..
Now don't talk while you drive!!......at least I see if someone is calling and then I stop and return the call when I am safe parked somewhere.
About $11.00 bucks
