Well. I went 1400 miles each way. 600 day one and 800 day two going up. I was one tired pup at the end of day two.
I took three going back much more comfortable. I will buy a windshield and lowers before I go on any more extended trips like Sturgis though. A windshield would have especially made those last 250 to 300 miles of a long day go much easier. You get tired of all that breeze in your face and neck.
