I had the kuryakyn risers on my b , I took them of and installed the HeliBars. I adjusted to where I thought they should be and went on a day long ride. They were not quite right so I pulled them all the way back then installed the kury shims that come with the risers . This raised them up three quarters of an inch. Several rides later I'm very happy with the comfort. I think I have my backrest where I need it in relation to my seat and bars. Now I'm fine tuning my ergo 111's to get that perfect fit for me. I'm planning a trip to Colorado from Nashville the end of May so all day comfort is critical. I love this bike more every time I ride it!
