I have many bikes pass through my hands every year. Only the Gold Wing and the KLX are what I refer to permenant members of my collection. Great bikes

.
I've had the KLX about 8 months and have put 3,500 miles on it, mostly off pavement. No issues.
It is a VERY narrow bike. I can stand over it and touch my toes underneath it. Its narrowness may make it better for people with shorter legs. If your GF will fit on it or not I don't know she'll have to hit the showroom and try.
It is much easier to straddle than a DRZ though, IMHO.
