These bar-end mirrors are top-notch quality, provide great visibility, and look so much better than the stock ones — that’s why they get a solid 5 stars from me.
That said, a quick heads-up on installation: the instructional video was a bit too generic and didn’t reflect my actual experience. Removing the original weighted bolts inside the bars was much more difficult than shown. I had to use a sacrificial M6 bolt (definitely not one of the nice ones in the kit), and even then, it took two of us with mole grips to finally get them out.
Also, in the video, the guy loosens the throttle and mirror assembly and slides it further up the bar — I found that totally unnecessary. Once the original weights were out, I just installed the new expanding bolts and everything fit perfectly.
All in all, I absolutely love the final result. These mirrors are a fantastic upgrade, and well worth the effort.
