This mounted easily and securely on my handlebars without marring the surface. It is rock solid. I'm confident it's not going anywhere.

RAM Mount should be the only brand you use!
I have seen too many falling phones with non Ram Mount phone and GPS mounts and will never use anything other than RAM on my bikes. Easy to install and multiple options for swing arms allowing you to customize where you put your phone. Simple system but strong and when installed correctly, won't budge!

Solid & Secure Cell Phone Mount
Hooked up my 1999 Buell M2 with this RAM Mount set up (U-Bolt base, short arm, and the universal cell phone holder). Holds everything solid and securely despite the rumble and vibrations of the big twin!

Federico M:This is just the base and that is for a handle bar. Go to ram mounts website and it will let you know what is the right dock for your gps device. That's how I did it. Good luck !Jun 24, 2014
