These would probably work ok as just standard bar ends..but they are useless for clamping mirrors to. Even cranked down as tight as i could get them they would rotate with very little force. Very poor design because at a certain point the nut inside the clip on that compresses the rubber will start to spin because it is not locked in place like most other compression type connections i have see.

look elsewhere if you want some good bar end mirror adapters. The CRG ones are fantastic

This item fit great. I didn't have any issues getting it to fit correctly. It does not move around with the Driven D-Axis mirror on it. Overall it is pricy but if you wan't a quality item sometimes you have to pay for it.

Excellent build quality and style, but rear viewing area in the mirror is minimal. The CRG Arrow offers much better viewing, still with great style. Also the Driven adapter vibrates too much with the bike, not a solid mount. If I were buying again, I'd buy the CRG Arrow mirror.

The rubber portion of this is supposed to grip the inside of the handlebars and then you mount your mirrors on the flat of the metal part. The rubber portion is not long enough for the throttle side (most throttle tubes extend 1/4" or so further than the handlebar's end) so only part of the rubber grips the inside of the handlebar and the rest of the rubber squeezes out and interferes with the inside of the throttle tube. The lack of rubber clamping area makes the throttle side mirror vibrate like crazy and it turns inside the handlebar. I had to constantly readjust the mirror because the heavy side of the mirror would "fall" to the bottom, pointing the mirror skyward. If the rubber were 1" longer, these would work great...but they are just too short for most bikes that have a throttle tube that extends past the handlebar. I finally got these working OK (not really acceptable though) by getting longer screws and longer rubber tubes. I made a sleeve out of copper pipe (to keep the rubber compressed under the throttle tube so the rubber wouldn't squeeze out of the handlebar and interfere with the inside of the throttle tube that extends past the handlebar) and bolted everything back together. This was a mess and I'm not happy that this was supposed to work with my bike. I had to do a lot to get these to work. I finally bought another pair of bar ends and bolted them to the stock weights inside my handlebars, using the stock bolt from the CB100R's end weights...and that worked much better.

I bought this product thinking it wouild fit my fz8 but apparently I was wrong. I am sure it is a good piece and it fits the mirrors great but it didnt work on my bike so it was a waste of money for me. Make sure you check to see if it is compatible for your handle bars before purchasing them.
