The mirrors came from Magical Racing in Japan. I like their looks on the Busa but they offer limited rear visibility even when adjusted to the "best" position. I don't really trust mirrors (I glance back often) so it is not really a problem for me but I think it WOULD be for many riders. The carbon fiber finish quality is high but they designed a screwy mounting system that I modified for a more secure installation. They are expensive and have too many issues for the money in my opinion.
