Great bar backs
First off, the machining and finishing on these are much better than on the generic imports you can find online. That doesn't mean that those won't work, but if fit and finish is important to you, then these are the way to go. Funny, I even found where one of the imports had copied a photo of these from this site and put on their Amazon product even though it clearly looked nothing like theirs.
The instructions are easy to follow. I will say that even being very particular about the installation, the throttle cables are quite tight. That is not the fault of this product, they just don't give you much cable to work with. In the end I completely removed the throttle cable guide and that seemed to help a lot. You just have to be sure that everything rotates freely like it should without catching on anything. A couple of strategic loose fitting zip ties helps here.
Adding these to my bike has really helped with the long distance comfort. The leaned over angle of the bike hurt my back after a while, and I never felt like I could really sit back into the pocket of my seat. I can now sit more upright and use my full seat. My back still hurts after a while, but it isn't nearly as pronounced as before.
I'm glad I picked these up.
