I just ordered a CRG Blindsight bar end mirror. It's only 2" in diameter. I like a sleek bike without mirrors.
I've been riding without mirrors for almost 5,000 miles now but like you said, it's time I keep a better look out for my ass when riding on the street. I only need the mirror for tailgaters and when stopped at traffic lights.
A soldier here from Fort Bragg was recently killed because a person ran him over from behind while he was stopped at a traffic light. He was a fellow R1 rider and more than likely a member here…
Another reason why I like my annoyingly bright CustomLED tail light. The brightest tail light on the market.
