Well had my AT now for nearly a year now, and find that even after 40 miles i get backache between my shoulders and back, so i decided to move the bars forward by 5mm and whilst it seems to have made the steering a little sharper which i like the back pain is still there. Im 6ft 2" so do you think the next thing would be to perhaps fit bar risers? If so what size? Or should i try something else? Anyone else experienced this problem?
