I've owned a 2010 RT, and I have to say that is one of the nicest bikes I've ever owned. In fact, I liked it better than my K1600GT in many ways.
It is quite light for a touring or sport touring motorcycle, which is something I really appreciate. The handling on the RT and the manner in which I could toss that bike around in corners is nothing short of amazing! It truly has sport bike like handling, and is also docile and stable at triple digits speeds.
The RT is not the speedster that the K16, or C14 are, but honestly, it's no slouch either, and is very torquey down low. I had a ball with my RT at Deals Gap!!
Enjoy them both!
