I know this is a purely subjective thing, but I will start: I have added about the value of my KLR in farkles, it seems, and they are all useful (guards, seat, heated grips, center stand, yada yada). But... The best dual sport mod I have made was putting on actual cleated off road footpegs. Free mod for me, as I had an old set off my dearly departed DRZ. hands down, I appreciate the confidence when standing and when in the slippery stuff more than all the "cool" SW Motech bits I have. Anyone else have a (maybe surprising) favorite mod?
