My 'trail' bike is an XR650L. Not for the short of leg, but way, way better on any non-paved surface, and capable of fairly serious dirt riding, even if I'm not. Weight is your enemy any time the surface isn't paved so just about any dual-purpose bike is going to be better than a DL for that specific application. On the other hand wind protection is fairly non-existent, vibration is more of an issue, carrying capability is more limited, and the DP's will be down on power by comparison. The KLR is a little better on road than the DR or XR, a little worse off-road. Almost all will be a challenge for the inseam-impaired, and any lowering (excepting a thinner seat) will cut into off-road capability. If you intend to ride in a fashion that will have both wheels off the ground at once in the dirt, get the lighter, smaller bike. But realize it will make you pay on pavement. Don't plan on selling the DL.
