This is far different from a RAM mount and may not be for you.
I had a galaxy s1 (captivate) and now my GS4 that I use mounted this way. No problems ever. It will be out of your vision if you're looking at the road ahead, but easily visble with a glance down. I use mine with the app DigiHUD (which is pretty sweet) on screen and in the background I'm running a music streaming app.
Mount to the top of the triple.
The otterbox come with a holster. I drilled two holes in the holster (after removing the belt clip) and zip tied it around the triple. The middle is right above the stem bolt.
You can just pop it in and you're good to go. Like I said I've never had a problem with it being loose or trying to fall out or anything.
That being said... ALWAYS keep your eyes on the road.. you really don't need distractions. I had a Sena headset so I can control the music with my left head while looking where I need to.
If you are wearing gloves, it will be hard to use the device.
I just open music app, start streaming, home, run digihud, pop in, gloves, ready to go.
edit: saw you have a tank bag, you may not be able to see it this way..
