WATCH YOUR SIX WITH BETTER FITTING MOTORCYCLE MIRRORS
Bar end mirrors are mounted like their name implies. They use expansion anchors to fit snugly in the ends of hollow handle bars. These are common on sport bikes and standards and allow the mirror to be at a wider placement. The wider placement allows for a wider field of view and has the greater likelihood of providing vision around the sides of your shoulders.
For most faired motorcycles, you have the option of fairing mounted mirrors. On bikes that require a full-tuck position, this style of mirror is a necessity. Because your head is positioned over the bars, the mirrors need to be mounted further forward. Aftermarket options with wider lenses and longer stems can provide a bit more coverage if you are having trouble seeing around your shoulders.
Once you have decided on the mounting style, you need to consider the type of glass that is used. Your options are either flat glass or convex glass.
Flat glass portrays the most accurate reflection of what’s going on behind you. It’s like any household mirror. The only problem with it is that flat glass does not have the widest field of view. If you go with larger mirrors and can set them up so that you can still see a part of your shoulder and directly behind you, then they are the way to go.
Convex mirrors are a great choice if you want an expanded field of view. Like the side mirrors on a car, they are able to capture a broader view, though it is a bit distorted. Like the sticker says, “Objects in mirror are closer than they appear.” Most mirrors are convex, so most riders are already used to the distortion. With that understanding, convex are a great option because they reflect more of what is around you.
Some mirrors do come equipped with blind spot mirrors. These are the small circular mirrors located in the bottom corner. These are more severely curved and provide an even greater view of what is behind you. You will still have a less distorted view from the main mirror.
Once you have decided on the style of mirror that will work best for your motorcycle, you will need to mount them. Vibrations can cause even the best mirrors to become blurry. To help prevent shaking on mirrors with mounting studs, use red Loctite on the threads. This will prevent them from loosening over time.
