Not sure if this mirror has been suggested yet but I have this on my RW4 and it works quite well thus far. I mounted it between my left grip and the bike controller making sure not to let the bolt touch the bell (which would make it inoperable).
When I have more time I will read through all 4 pages and study the list a bit more,.
Thanks for putting this list together @Ryan
