Yeah, Someone in a minivan had one and they were so busy playing with it that they almost killed me.
They suck.

 

Look at the Quad Lock mounts. I have tested them at over 110mph on naked bikes (of course on closed course circuits only <cough>).

Super solid, low profile and you can mount all sorts of things. Cellphones, GPS, heated gear controllers etc....

QuadLock

Personally, I use the bicycle version cable tied to the bars rather than the motorcycle specific version, but that is because it is lower profile and I can swap between my bikes and bicycles in no time at all.

 

Ram Mount holders. Took a 4k trip and never had an issue.

 

 

 

 

You're gonna get lots of suggestions about the "Hawg Hook" and the "Maxi Mount" and the "iStay", and whatever the newest motorcycle rally vendor startup of the season is.

Save yourself time and money, and just get a Ram Mount X-Grip phone mount. It's simply awesome. It's universally available, and it's a sturdy, secure mount to mount your device on your bars, putting it in a perfect position for charging and navigation.

 

Use the RAM xgrip also, well used it. Works great, also very easy to put your phone in and take out. Some of these mounts take forever to get your phone in and out of watch out for that. It'll just annoy you.

 

I've been using Ram Mount X mounts on ATVs, my zero turn mower and my Road King. I've never had an issue at all. I won't buy anything else. I've seen several cheap all plastic mounts break over the years. But never seen a broken Ram Mount unless it was in a crash.
