I commute daily on the KLR 80mi round trip to work and back, like you, to save gas money.
I load it up with all the bags and have done 5000mi highway touring, occasionally taking a nice trail or fire road fully loaded.
I have ridden my KLR 75mi to get to the trail and then did a 50-60mi trail ride and then another 75mi to the first gas stop back in civilization.
While it wont do what a real MX bike will do and its not as comfortable as a Honda Goldwing, I believe its a nice compromise that allows you to do a little of everything and just about anything you could want to do on a motorbike.
If that sounds like what your looking for, than the KLR is for you.
