Summary

Tired of looking at your arms in the rear-view mirrors?

A set of mirror extenders might help.

There are many different types, one of which may fit your motorcycle.

On the BMW F 800 S, the stock mirrors look nice but they're virtually useless.

The SW-Motech mirror extender blocks described here solved the problem.

Introduction

Too many motorcycles have poorly designed rear view mirrors. But there is a solution...if you're lucky.

We've covered this topic before, with the mirror wideners for the Suzuki V-Strom 1000 ABS.

Also made by SW-Motech, they move the base of the mirror out about 40 mm and up, which added about 20% more rear visibility.

Those are available for many different motorcycles that have the basic type of mirrors that screw in to adapters on the handlebar.

Some motorcycles, like the F 800 S, have the mirrors mounted on the fairing. This calls for a different type of mirror extender or widener.

The SW-Motech extenders shown here are basically a block or wedge extension that also adds about 40 mm to the overall width on either side.

They look a bit strange at first, but I soon became used to them and now they just look like part of the bike.

While they don't provide a perfect rear view, I now get about 60% of the usable mirror vs. no visibility at all before.

They're very easy to install; let's take a quick look in pictures:

Here's the stock mirror base on the F 800 S. The SW-Motech extenders fit between the base and the fairing.

See second photo above, this bolt serves as the "knuckle" of the BMW mirror to allow fore/aft adjustment of the mirror arm. Tighten it to increase friction. I added the wavy washer to help improve the friction because the mirror arms have become loose from too many adjustments by the previous owner.
SW-Motech Mirror Extenders
The SW-Motech kit for the BMW, Kawasaki and others uses CNC-milled "PA6-MO composite" extenders. The kit comes with the longer SHCS bolts (these are 70 mm long).

Conclusion

SW-Motech makes quality accessories and I have installed many of their products on the Suzuki DR650 (Blog), the Suzuki V-Strom 1000 ABS (Blog) and now on the BMW F 800 S (Blog).

Old-timers like me will remember the days when none of these helpful accessories existed. Unless you could figure out a solution on your own, you were, well, on your own.

Basic mirror extenders for screw-in handlebar mirrors have been around for a while, but now it's good to know that there are many other types available that can even fit bolt-on mirrors which are mounted on a fairing.

Note, however, that depending on your physical dimensions and the motorcycle, you probably won't go from no rearward visibility at all to full visibility. A good example of that is these SW-Motech mirror extenders mounted on the F 800 S.

But at least I have some visibility to the rear; I had absolutely zero before.

These don't come cheap, however. The going price for this type of extender for various motorcycles is $83.95 the pair. But since you couldn't make a set that looks so "OE" unless you owned a fully-stocked machine shop, you don't have much of a choice.
