Since the product is a convex mirror, it is normal to have some space at the edge of the rearview mirror after installation. The convex mirror will make the rearview mirror thicker and cause it to protrude slightly, which is normal and does not affect mirror usage or viewing area. If the motorcycle's rearview mirror lens is cracked but still in place, the convex mirror can be directly applied onto the existing lens for easy installation. However, if the lens has completely fallen off and only the mirror shell remains (without lens), the convex mirror cannot be installed. Installation: Clean the motorcycle's rearview mirror lens thoroughly. Peel a small section of the backing tape from one corner of the convex mirror, align it precisely with the mirror lens, then gradually remove the remaining backing while applying the mirror from one point outward across the surface. Avoid pressing the convex mirror lens forcefully after application to prevent damage. After installation, the field of view through the motorcycle's mirror lens will be significantly increased (approximately one-third wider), helping to reduce blind spots and enhance riding safety. Compatible with rearview mirrors only. Not suitable for modified rearview mirrors.
