Happy trails, touratech, SW motech, Wolfman tank bags. I've had a few klr's plus a DR and 4 BMW GS's. KLR's get a new seat, new aluminum bars (renthal 666 desert bars)and gel grips, happy trails skid plate, foot pegs, progressive springs, stainless front brake line and galfer pads, set of Dunlop 606's and a Wolfman tankbag right from the start.

If buying used, find one with as many of these things already done as possible. Usually adds very little to resale value but cost thousands if you have to do it.
