Great mount but needs mod on 2012CBR1000RR
This thing is great. I do a decent amount of comuteing and this makes it so much esier to have my gps music and even messaging (at stop lights of course) at my finger tips.

However I bought this because I thought it said it would fit on my 2012 cbr 1000rr. It alas did not :(. The rubber insert was to small (cone section) or to large(straight section) for the steering stem. This problem was easily solved with a quick trip to the hardware store and $1.11. I purchased a 1" rubber stopper and a washer that fit better than the ones provided. I sanded the stopper down the the appropriate size ( much less than trying to sand the straight part of the rubber provided). I thin drilled the stopper out as well as the washer. Then I assembled as directed and it worked great.

Side note I over tightened the screw to fast and It heard up the nut/washer combo and pulled the nut through the black bottom washer. So do it slow and steady

High quality mount, just what you'd expect from RAM
This is another great mount from RAM. It provides a very clean install. The instructions were clear and the kit included all necessary hardware making installation a breeze (we installed it in a parking lot with a multi tool). I have no problem recommending this mount.

It does it's job, but you need to be careful
The install was good. Instructions, good. The stem bolt head stripped before I could tighten it to the needed level to stop the mount from turning from vibration. I contacted RAM and they are sending me out another bolt for free. The lifetime warranty is a definite plus. However, I think that the rubber stopper in my case, may have not been cut properly and is too large and that could be my, and others issue. Either way, they are a decent mount system. For the guy below who said the arm is too long, they do have different sized arms you can order. I felt it's too long as well for me but if you angle it and play with positions, I managed to make it work for me.

Great Product
I don't have a ton of bar space on my 2018 CBR600RR so i was looking for different products to mount my phone for GPS and general music. This seemed to fit the bill the best. Install was a breeze. They actually make a youtube video for it

This makes it even easier to install. Had it out of the package to installed in my bike in 10 minutes (only reason it took so long was because my fiance wouldn't stop asking me questions about my new bike)

It works perfect, Got the additional attachment to hold my Galaxy note 8. Couldn't be happier with how its used.

the only problem I had was the base would swivel at the connection to my steering tube. I set it with a little epoxy between the plate and the top of the steering tube. Seems to be holding up and I got some great footage on Hwy 2.

Very nice mount but...
The mount will do its job your sure but i feel like it wiggles little to much... Don't get me wrong I love this product and recommend it. The quality of the mount itself is excellent feels very durable.

Twists too easily and the arm is really long
After installation I noticed that the stem mount turns too easily and will not stay firmly in one spot, no matter how tight it is. Also, to get a good tuck behind my small windscreen, the arm has to be positioned straight back over the tank or forward over my key to keep out of my helmets way. It is kind of irritating because my helmet bumps the phone when it is positioned over the tank and distracts me while riding on the track. Position to the front and you will find that it almost sit on your key if you have your legs thrown over an S1000RR or HP4. Also, it will block the speedometer and rpm gauges as well. The arm that connects the balls on both ends is too long. Wish they made a compact version. You should be okay if you are just riding on the street. As for my riding on the track, it does not meet my expectations and I am going to return this through the manufacturer.

Absolute trash
I have been through 2 on my 2017 zx6r so far. Followed the install vids both times, damn things fall right out under and pressure. Never even got a chance to mount my camera because it was too loose. Tighten it and it pulls out

I've been shopping around for a long time for a way to bring along my GPS/ phone and this was the winner! Got very good reviews and I love the integration into the existing part of the bike. Can't wait to get it and install!

I was looking for something that didn't mount to my handle bars because I didn't want to limit my turning radius. I was also looking for something that would block my view of the gauges. With this RAM stem mount I'm hoping it's centered and low profile.

What is the length of the double socket arm? Thanks!
amy n on Jul 6, 2014
BEST ANSWER: The piece that comes with this kit is about 3.5" long. I ordered a separate socket piece that is about half the length and I prefer it much better for my setup.

would this fit on a harley sportster? Saw some advertised on ebay with a list of bikes that were comparable, couldn't find any Harley's on the list.

Mohammed F on Jul 19, 2014
BEST ANSWER: The best way to make sure it fits is too look at your bike. This mounts to the steering stem if the stem is hollow it will fit. There may be a cap ontop of the stem that can be removed.
will this fit a 2011 750 gsxr?
Toan L on Mar 10, 2014
BEST ANSWER: This is universal. I originally got it for my 2012 honda CBR 250R and now I have a 2014 honda CTX700ND. This is the complete kit. When you are ready to take it to the new motorcycle, just call and get the expeding rubber. Ps the metal oring is very sheep and not plated so it will rust on you bike so just go and get a rust proof one.
A S on Aug 4, 2015
BEST ANSWER: Man it is big, but I just dont know. My buddy put his iphone 6+ in it and it fit. Not sure about the note.

Ram's website tells you the dimensions it will open .
