    Works great for larger handlebars that wonโ€™t accommodate most clamp on style phone mouts.

    I bought this because there weren’t many options that would work well with my Continental GT 650’s factory clip ons. This was easy to install and works perfectly for mounting my phone with a ram mount arm. The best thing about it is when you’re not using it for holding your phone or GPS, it doesn’t stick out and ruin the look of your bike

    Mounted very easily, did not have to remove the original clamps, thanks to long bolts.

    Very solid, tested with a RAM Mounts X-Grip, and a Samsung Note 4 on a 2.5 hour trip between Windsor and St. Thomas. Phone barely even vibrates, even though it’s held outside of my windscreen’s protection.

    Amazing build quality, this thing is what confidence feels like. Has some weight to it.

    This mounted up ok and feels solid, after I went to the hardware store and bought some stainless washers and zinc plated steel bushings that fit the size needed. I used the 1/2″ L X 1/4″ ID steel bushings backed up with some #12 stainless steel washers that I put under the lock washer at the screw head and on the other side of the mount body for the steel bushing to press against. The holes in the mount body are a sloppy fit for the supplied screw head and lock washers. The supplied plastic bushings don’t properly fit the OEM handle bar clamp or the Ram Mount screw holes. The steel bushing I bought was the same OD as the OEM screw head that held the master cylinder to the handlebar. That made a perfect fit to the handlebar clamp so a washer etc. was not needed at that end. Bottom line, it will do the job nicely, just needs a little extra in the hardware department.

    I did a video installation of this phone mount: […]
    It fits my 09 ZX6R perfectly! Any models from 09-12 are the same BTW
    My video explains it all but for short…
    PROS:
    Sturdy and great materials
    RAM makes the best mounts
    155mph does just fine (obviously on private roads;))
    I get lots of compliments and Q’s about it and people love it!
    It does not get in the way even with my Cortech tank bag which covers the whole tank
    CONS:
    None at all

    SUMMARY:
    I did not get paid by this company although if I were sponsored I would stand behind their products since they are just that good! You gotta give credit where credit is due!
    I’ve used RAM for 2 years now and have never had my phone or GPS fall off
    5 Stars No complaints
    I would recommend the center triple tree mount as that has the best viewing and cosmetic appearance however this mount allows it easier to see the phone plus it is much cheaper

    When I received this it appeared as it had been used before. There were some scratches around the screw hole area. It was easy to mount on Gold Wing. I have no complaints about quality other than the previously mentioned scratches. The looks are fine other than the scratches and I think it is made well and should last.

    Little tricky to install and at one point I dropped a washer into my bikes fairings so had to strip the entire front end….. but once installed itโ€™s a solid product and with the RAM short arm and Xgrip, itโ€™s a perfect phone holder for my Ninja
