I made my first long road trip today. From my house to Maryville, tn. Getting up in the morning to go ride the dragon and any other mountain road I can find! I rode for a little over 5 hours today only stopping to get gas. I had a back ache and my tail bone was hurting within the first 50 miles. I'm 6' 3" and 270. What's a good seat for somebody like me?
