I have a friend who rides a C-14, he is very KAW loyal.
It depends on what you want. When we ride together he is tried after 300 to 500 miles, while I can easily do 700 to 1k. On a straight away he is quicker on the start, but above 40 miles per hour I can stay with him. In the curves, my GT has no problem with the C-14.
The GT2 is 8k more, but for me the GT2 is better two up, better luggage system, and better stopping power. Then you have cruise, heated seats and grips and don't discount the ESA.
For me I will make up some of the 8k difference in resale and I believe I will be able to put more miles on my GT2.
Besides can't you get $1,200. off right now for a new '08 GT2?
