Just started riding a 04 r1150rt coming from a stop light to stop light Harley. I was curious how long it takes or how many miles before your backside, shoulders ect ect...get use to the longer distances. The bike is totally stock and before I start playing with bike add on's, I was looking for some rider advise. I know at times I am hanging on to tight and try to relax my posture, but after an hour or so I start getting a sharp burning sensation in the middle of my shoulder blades. I suck it up now because of the Nube factor...hoping it will get better as I ride more. Any thoughts?
