I know KLR are prone to falling over when loaded ...............
Here is my quick solution......a piece of unistrut jammed as shown then just use bungie cord for wrapped as shown to keep tension, actually rock solid ! works for me!
Any other ideas out there !
(O.K. could not find how to put picture with post so here is a description: It is a 28 inch shallow unistrut inserted just under the top bolt of rear foot peg bracket and bungie cord is wrapped around lower portion of unistrut and my center stand, of course bike is not on center stand or this would not necessary, by the way it is almost possible for me to put bike on center stand with my happy trails panniers on otherwise I would just do that.)
