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.


  • 6061-T6 aluminum CNC machined billet construction
  • Black anodized finish
  • Compatible with CRG LS series mirror
  • Sold each

Application range:

  • 7/8" size range 12mm to 19mm ID
  • 1" size range 18.3mm to 22.25mm ID

Fitment Notes & Exceptions

CRG Billet Internal Adapter For CRG Bar End Mirror 4.5 5 40 40
Easy to install, excellent craftsmanship. I bought this as part of the CRG Bar End Mirror. Works perfectly. Super easy to install and well made. November 16, 2015
Functional lightweight. For some reason i thought this would come as a set of two. Received my order had to order the other side. So $40.00 for the set kinda pricey. I wish it would sit flush against the bar end, it starts to come out of the bar once you tighten it down. I git it decently mounted but theres a tiny gap still, no bill deal im just very picky. Very easy to instal and goes and looks great with the lane splitter mirrors. Ill add a pic later. October 26, 2015
CRG Bar end adaptors I am not very handy- but the CRG lane splitter mirrors and bar end adapters took me only 20 minutes to install on my 2012 Ducati Monster 796. Great product! Love Revzilla! This is the only place I get my gear from! October 15, 2015
Amazing product, could be cheaper Really nice, easy to install bard end which perfectly fits with CRG bar end mirror. Only complaint is the price considering size and functionality of part. October 5, 2015
Quality Part This is a very well made part and it functions very well. August 3, 2015
Works great This fit my woodcraft clip on bars without any hassle. Looks solid! July 20, 2015
Good stuff, didn't need it, kept it for future I purchased this adapter to mount my CRG Hindsight Lanesplitter mirror to my 2015 Yamaha FZ-07. Turned out I didn't need it, because the mirror mounted perfectly to my left side bar end weight. Decided to keep the adapter for a possible future installation. Love the mirror. July 15, 2015
Great for CRG bar end mirrors I use these with the CRG lanesplitters on my Street Triple R - they look good, they hold well, and they fit CRG mirrors like a glove (duh). I had one low speed lay down after hitting some paint in the road while leaned over quite a ways, back end washed out. Bar end did its job - handlebars are unscathed. Unfortunately, one lanesplitter mirror was ruined but that's the way she goes with bar end mirrors. Pricey little suckers IMO but if you use CRG mirrors, you won't find a better fit. July 13, 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
Answer this · Send to friends Good question? Yes (2) No (0)
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
Reply to Derek Good answer? Yes (0) No (0)
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

A shopper asked: I have a 2014 Ducati Monster 796, i took off the end cap of the handle bar and looks like the inside is hollow with nothing to screw the adapter onto. Does it just snap into place with the 7/8 attachment? Ive seen videos where the adapter has to be screwed in with an allen wrench.. thanks Aug 7, 2015
Answer this · Send to friends Good question? Yes (0) No (0)
ROBERT S: It's kinda fiddly. You have to put the pieces of the adapter together kinda like a puzzle. Depending on the diameter of your bars, you might need all four metal pieces (for larger bars), or just two (for skinner bars). Then, sort of holding everything together, you slip the adapter inside your bar and start screwing with the allen wrench -- the farther the screw goes in, the more adapter expands, and the pressure against the inner walls of the bar holds it in place. The really hard part is making sure that the all of the little metal pieces stay in the proper orientation while you're screwing -- if they fall out of place, then the screwing/pressure doesn't work, and you have to start over. Or--God forbid--if you drop one and it falls down inside your handlebar, they're not magnetic, so you'll have to fish it out with a coat hanger or something. Aug 10, 2015

Allan P: I understand, i thought the screw was supposed to attach to something inside the handlebar, didn't realize its used to expand the adapters against the inside of the handlebar....will try, and thanks for the reply Robert S..great help!!! Aug 17, 2015

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
