Even after spending $500 on a Harley backrest I can't get comfortable on this bike. My back, mostly upper, and shoulders ache after a few miles. I've rode bikes for years and never had this prob lem before. It feals like I am reaching for the handle bars. I am 5-11 and 180 lbs and my feet can sit flat on the pavement no problem. Before I waste more money does anyone else have this problem or a solution for it. Thanks.
