I just finished my first what I consider long ride. I'm not sure if its the stock seat or my conditioning but I had a hard time staying very comfortable. I did 400 miles and really after 200 I was starting to get wore out. I know proper form for riding as per master yoda and it wasn't my back or my arms that were tired. It was mostly discomfort in my posterior section. Would a sergeant seat make some difference here? I am planning for a 850 mile one way ride to try out dragons tail, cherahola, and the blue ridge skyway and am just wondering if maybe I need an aftermarket seat or just more conditioning. Any ideas. Forgot to add I have an 03 GT.
