I just installed one on my Kymco like 200, very good quality and looks good. however, be aware that you will get a fair amount more wind blast around the helmet area. it does keep you from being pushed back at higher speeds. the brackets on the Kymco also moves your mirrors out farther which is good.
I too, have a 2021 honda super cub and would be curious about your thoughts after you try one. I find the cub to be a blast so far
