This is Sunday morning on May 30, 2010. Southbound on Highway 550 somewhere near Ouray - not the "dangerous" portion. Although it was late spring, it felt and looked like a sunny winter day. High elevation. The Colorado Rockies are, without a doubt, the best roads for motocycling and scenic vistas. I am riding a 2007 Suzuki C90T. The bike in front of me is a 2004 Yamaha Midnite Venture. My bike didn't like low RPM's at high altitudes. It tended to stumble a bit, but nothing severe. If you haven't ridden thru the Rockies, you just haven't ridden. We are going back in September with our group of 6.
