Installed the HeliBars Tracer90GT riser today and I have to say it put the bars in a perfect position for me. I'm 6'1" and have the comfort yamaha seat and the bars ended up being a bit too forward and down. The HeliBar puts it up and back in just the right amount to destress my shoulders and relax my arms. My tracer was already an all day ride but now I'm very comfortable. 100% perfect upgrade.
