I installed my MBL risers from HDL last night. Took about 30 minutes. Was very simple and straightforward. I sat on the bike and could notice a difference immediately. They do move the bars from the sport bike style to more of a GL1500 setting. I have ridden several Gl1500's and the new setting of my bars is very simular. Took a ride and did find that the new setting of the bars will require some adjustment. Not a lot but some all the same. I can already tell that they will help with the upper back burn. I have short arms and can now reach the grips much easier. I see a much more relaxed posture in riding.
