I agree, you need to maybe look at the seat, shock, tire combination and do some tweaks. I hear the progressive rear shocks make a big difference in the ride. On my last trip to Eureka Springs, I had my tires at 44 and that was way too hard. 32-34 would be better. I can do 500 plus days on mine. I'm numb and tired, but you would be on anything after 500 or 600 miles, even a Goldwingie.
