The mirrors are mostly an aesthetic upgrade from the stock antennae-like appendages but—with about the same glass size—provide comparable rearward visibility. Two things strike me as odd: the blue-tinted glass and the limited lateral adjustability of the mirrors on their stems. Turns out Rizoma uses the same anti-glare glass as Audi, which gives it that blue hue. The tint takes a little getting used to but otherwise isn’t a problem. Sometimes the mirrors are difficult to adjust, but I’d rather they were a little challenging to move than loosey-goosey. Aside from that, I’m enjoying the upgrade, both on and off the bike.
