I agree. Somewhere I have a sketch showing the difference between a Z50 (softail), K0 and K1 and up. There are a lot of variables on handle bars and the top plate/mount plays a part. Not sure about the CHP bar dimensions or the stance, but from what I've read, they are the best of the lot when it comes to aftermarket bars. I've only had one set of aftermarket bars (non CHP) and they were for a soft tail. The chrome was ok, but that's it. Nothing fit, and the tubing was just a notch above a shower curtain rod. On the plus side, they were easy to straighten.
