The mirror looks bigger than what it really is. No not built in, this is a pure Polaris parts mirror. As I look in mirror it shows just the top of my head overlooking rear. I have it off set from center because rear view mirror in center will not work with MTX stereo. I go on tight trails occasionally and don't want to run the risk of smacking off side mirrors.Is that a built-in rear view mirror (not aftermarket)?
While wearing a helmet, can you see anything other than your own head through it?
