Hello and welcome. I'm slightly smaller and lighter than you, but I suspect the 650 might actually be tailored a bit more to your size. I can just reach to get both feet down firmly, and I installed up and back risers to feel more comfortable reaching the bars. I'm considering adding a tooth to the front sprocket, which is now probably just right for a heavier rider. I don't ride a lot of miles, as most of the guys here do, but I'm persuaded the 650 is the right bike for just about anything I want to do.
I had the chance to ride several new bikes at the local dealer's demo day last weekend. I rode a 1000 V-Strom, an Africa twin, a Suzuki SV650, a Honda NC-750, and Triumph Thruxton R 1200. All were excellent, but I was glad that the one I own, the one I rode home, was the DL650. DD
