Cool, it looks like a good option for mirrors, right now I'm width limited, squeezing in between shelves and a project car that's up on stands. Hopefully that will be remedied soon. The car needs to get back onto its wheels.
Most of those mirrors seem to be in Japan. I'll keep an eye on them for the future, the K1/2 Rat Race has the same issue, one similar mirror on CB400F bars.
