CRG Billet Internal Adapter For CRG Bar End Mirror

This is the Billet Internal Adapter for the Arrow, Hindsight, Hindsight LS and Blindsight Billet Bar End Mirrors. CRG makes this assembly to offer an alternative to the basic Bar End Mirror mount. 

Whenever possible, CRG recommends mounting the Hindsight Billet Bar End Mirror with the basic mount which clamps to the outer diameter of a 7/8” handlebar/clip-on. Using the basic mount is the bar end mirror solution using the fewest parts, facilitates the easiest installation and removal, is the lightest weight, and provides for the most secure bar end mirror mounting. Use of the basic mount requires having 10mm (3/8”) of bare bar outboard of the grip/throttle assembly. Before purchasing the mirror adapter, try moving your grips and controls inboard (away from the end of the bar). In many applications, the mirror can be mounted with the basic mount.

CRG Billet Internal Adapter For CRG Bar End Mirror 4.4 5 32 32
Not for Ninja 300 This adapter looks very well made and looks like a great product however if you own a Ninja, this product is not compatible with the bars for this motorcycle. This adapter is for bars which when removing the bar end weights is hollow, as opposed to threaded. June 16, 2015
Great At What It Does, Could Do More Does exactly what it says it will, easy to install, and good quality. It'd be nice if you could select different weights given that these replace any weighted bar ends you wanted to use, however. Also, it's be nice if there was an option to put delron protectors on the end or something to protect from damage if your bike is knocked over or if you spill. May 24, 2015
Perfect for 848 EVO Perfect fit for my 848 EVO, Product was shipped on time, actually early and did exactly as it was intended for. Made my book look very very clean once installing the CRG hingdsight LS mirror May 19, 2015
A must for your bar end mirrors First off I didn't like the idea of having to buy another part in order to put the bar end Mirrors on my bike but the CRG adapters work very well with the CRG mirrors and the combination of the two work extremely well together. May 11, 2015
Does it's job beautifully, but... First off, this product works just fine. My blindside mirrors fit perfectly into the adapter for a very appealing result. Install was pretty easy, but creates a few issues (will explain later). While install is somewhat hard to explain, all you have to do is throw on the little pieces and tighten using an allen wrench. At first you will wonder how it will ever work, but it will. I only needed to use the 2 base pieces for my FZ 09, as the handlebars are thinner. Here are the issues, which is less about the product and more about bar end mirrors in general. 1) Be careful installing the throttle side adapter. Stock bar end weights are designed to fit nicely around the throttle to not get it jammed. If you install these adapters too close, they will restrict the throttle from moving properly. Obviously a stuck throttle is a bad throttle. Also, installing these adapters too far out will allow dust/water/ debris to get inside the handlebars. So you have to play around with it to get it as close as possible without restricting the throttle at all (or do some surgery on your grips/ bars). 2) bar ends are weighted for a reason. It keeps the handlebars more stable at higher speeds and generally helps with maneuvering the bars and therefore the bike. These adaptors are very light, so you lose the bar end weight aspect when installing them. Both of these are pros and cons you have to take i suppose though when switching to bar end mirrors. One last tip, make sure the bike is level before installing the adaptors. Heard several horror stories of the pieces breaking loose during install and falling into the handlebar. Fortunately, install is so easy that you can technically do it while sitting on the bike (for those without a vertical bike stand) March 16, 2015
Fitment issues with BMW S1000RR (all model years) While this is a quality made product this will not install on a BMW S1000RR without extensive modification to the handlebars or replacement of the stock handlebars. The stock design has threaded internals that secure the stock bar ends. You will have to mill out the internals. This is not easily done, who has a vertical mill available? The other option is to put clip-ons on the bike. This is difficult due to the stock setup and how they connect to the triple, they are not "clip-ons". The easiest route was to order new bar ends from Rhino Motorcycle Products. They designed a weighted bar end or unweighted if you prefer with a notched section to specifically fit the CRG handlebar brackets. They secure into the bar ends using the stock M12 bolt. A pair will set you back about $80 with shipping but it's cheaper than switching to clip-ons. February 24, 2015
Straight forward install, as long as there isn't a custom application Easy peasy install on the clutch side. Throttle side can be challenging to prevent the adapter from rotating or causing friction/resistance with the throttle. Depending on the grips you have, you may run into issues. I have Kuryakyn Iso-Grips installed on my Harley, and a Brakeaway cruise control device, so it presented a need for modification. See the video for how I got it to work. January 20, 2015
So easy to install Didn't want to move my grips and levers and reservoirs. These billets made accommodating the mirrors without too much work so easy. January 19, 2015

A shopper asked: I purchased this product to adapt the CRG Arrow Bar End Mirrors on my 2015 Yamaha FZ-07. The none throttle side works perfect, however, on the throttle side when the adapter is tightened it causes the throttle to stick. The grip is completely clear which I read elsewhere that was the issue in some cases. Any suggestions on a solution? Aug 15, 2014

William G: I installed mine on a 2014 FZ-09, which probably has similar bar end configuration. The handlebar weights thread into the handlebar and form the end of the handlebar surface. Once the stock weights are removed, the actual handlebar is recessed into the grip about .5". That is why the adapter causes drag on the throttle; obviously and an unsafe condition. It was not feasible to re-locate the controls inward due to space. The only proper solution is to replace the handlebar with an aftermarket handlebar that allows the end of the handlebar to extend to the end of the grips. I used a Renthal Fatbar on my FZ-09. The FZ-07 uses a conventional 7/8" tubular handlebar; finding a suitable replacement should not be difficult. Aug 16, 2014

Derek L: I haven't bought the adapters, but I felt like I would have the same problem. I also have the FZ-07 with the CRG Arrow mirrors. My solution I am going to try is to find either a VERY large set screw, or if the handlebar isn't hollow all the way through, put a metal spacer that the bar ends will tighten down onto, bumping them out just enough to attach the mirrors. Oct 3, 2014

Ken L: You need to create a space between the outside end of the handlebar/throttle and the inside of the adapter. I did this by using zip ties to create a standoff between the two when tightening.

See my review and video i posted on how I installed the adapter.

Answer this · Send to friends Good question? Yes (1) No (0)
Clarke B: They can mount on the end of the adapters, but you would need longer bolts and you would most likely have issues with them being in the way of properly adjusting the mirror. Also, most bar ends have a ridge and are not flat on the side that mount to the clip-on. Jun 24, 2014
Reply to Clarke Good answer? Yes (0) No (0)
Gerard B: that's a good question. i think that if you customize it, you would have made a new product for this manufacturer to make. just saw of the bottom insert of the bar ends and use a longer screw and you got yourself a winner Jul 19, 2014

Ken L: It uses a M6 Capped bolt. The nut's pitch used isn't a common size that I could find at the local hardware store (.5 and .7). The threading looked to be a .6 if I was guessing. If you're careful you can force thread it (deliberately rethread it). Jan 20, 2015
