1. Since the product is a convex mirror, it is normal to have some gaps at the edge of the rearview mirror after installation. When the convex mirror is applied, the overall thickness of the rearview mirror will increase slightly, causing it to protrude a bit, which is normal. This does not affect mirror functionality and helps enhance visibility.2. If the rearview mirror lens on your motorcycle is cracked but still intact, you can directly apply the convex mirror onto the existing lens for a convenient upgrade. However, if the lens has completely fallen off and only the mirror shell remains (no lens), the convex mirror cannot be installed.3. Installation: First, clean the surface of your motorcycle's rearview mirror lens thoroughly. Peel back a small section of the adhesive liner on the back of the convex mirror, align it precisely with the mirror lens, then gradually remove the remaining liner while carefully applying the mirror from one edge to the other. Avoid pressing too hard after application to prevent damage to the convex mirror.4. After installing the convex mirror, your field of view through the mirror will significantly increase by approximately one-third. This helps reduce blind spots while riding and improves overall riding safety.5. Designed to fit original equipment rearview mirrors only.
