What about the difference for the passenger. We have a Spyder RS SE5 that we bought new in 2008. It is nice and my wife does not want to trade it for a RT. I rode a GL1800 CSC trike with 6 degree triple tree last week and I liked it alot. Handled better than I thought it would in the curves. My wife was not with me so I don't know how the back of the trike compares to the back of the Spyder? To me the Spyder is good if you are driving but as a passenger you get whipped behind the front wheels and it is not as enjoyable.
