It begins with 40 miles of 80mph+ highway on a warm day. In addition, it was into a fierce headwind with gusts. The windshield was helpful if I scrunched down behind it, but the Sertao is not happy at those speeds. It feels tight, and gets above 5500rpm on the tachometer. At the conclusion of that run, I immediately ran into city traffic where we crawled along in fits and starts, and really tested the clutch. Then after a break, it was more city traffic for 30 minutes followed by a highway blast to finish things off. Not the expected outing for the Sertao, but a good test of high speed bike, slow speed bike. It handled both, but did not feel happy about either.
