Free: Contests & Raffles.
I am going to politely disagree with Altroxus. I would not go with a KLR or its Honda rival (XL650). Both have high centers of gravity, and are heavy!It sounds like you have gained a few years since you last rode. You will be surprised how much strength you have lost in your upper body. You do not want a heavy bike in the back country, especially when you are tired. Compromise on the "comfortable at 70mph" condition, and go with something road legal but much smaller, such as an older XR250. Cheap, lightweight, easy to maneuver, easy to repair. The XR is quite tall, so maybe not a good match for you, but do look at smaller (displacement in c.c.'s) bikes.I sold my 650 two years ago. Too heavy for single track, not fast enough for the freeway, dual sport bikes are bad at both. Never again for me.
I'm not sure there is such a bike that is:1) lower seat than a TW200 and2) goes 70mph on the freeway and3) comfortable for 100+ mile ride and 4) light enough for a hitch rack under 500lbs 5) and off road capable for sand washes + carry a gun boot.
