I have an 2003 st 1300 and am planning a major trip in a couple of weeks. I love my bike so just want to enhance the great ride. I am looking for a set of highway pegs so I can have a different leg position and hopefully get some extra distance between stops. I have a set of the heli bars bar backs which seems to help my back and arms. My butt still gets tired and my legs cramp up after a few hours. My knees seem to get tired and sore so any advice would be great.
