I trailered my 2008 out to Colorado then spent 8 days covering 2500 miles of every scenic road I could. Recommended roads are 65 from Cory to 70 over Grand Mesa, 149 from around Gunnison to South Park (then 160 to Pagosa Springs over Wolf Creek Pass), Skyline Drive around Canon City (3 miles and not to be believed), 92 in the Curacanti National Recreation Area, 82 from Glenwood Springs to Aspen and Independence Pass, 131 from Wolcott to 134 to Kremmling over Gore Pass, Kremmling to Steamboat Springs on 40, 40 from Kremmling to 14 to Fort Collins over Cache de Poudre Pass, 305 from Buena Vista to Cottonwood Pass, 141 from Vancorum to Orchard Mesa (be sure to get gas first), and maybe 40 from Empire to Granby (Berthoud Pass).
The Versys ran great everywhere on everything, including 8 miles of gravel, rutted, washboard road from outside Chivington on 54 to the Sand Creek Massacre National Historic Site. Idle speed dropped to 1000 rpm because of the altitude.
Scariest moment was descending on 550 (the Million Dollar Mile) toward Durango when it started raining followed by hail.
70 tends to be a wind tunnel so consider this fair warning.
Heated grips and the Aerostich Kanetsu heated liner came in handy when the summit at Rocky Mountain National Park was 38.
I saw a lot of interesting bikes: many Harleys, of course, being ridden by rather old people, lots of VFRs (having a rally in Montrose), 2 guys on Kawasaki Eliminators, 3 other Versyses (each blue, mine's red), 1 Aprilia Tuono, several Ducs and Multistradas, V- and WeeStroms, many GS1200 Beemers, FJR1300s (a popular sport-tourer), a couple of Kawi Concours 14s, and even a 1980 KZ750 (4). I don't think anyone had more fun than I did though
