I installed it immediately. Although the curvature rate is not described in the item description, this mirror is a curved mirror of 1000R. It is light purple and fashionable, but it is slightly darker. Since it is a curved mirror, it will make it easier for you to see a wide range, but until you get used to it you will not be able to grasp the sense of distance. During running, the blurring during idling has almost disappeared (single cylinder car) I think that the mirror is suitable for a small small movable range.
