Works like a charm!
My Audace has Bluetooth which interfaces with the Moto Guzzi iPhone app to display various pieces of information about my bike. The Audace, like most cruisers, doesn't come from the factory with a phone mount. I went to a local motorcycle accessory store (sorry Revzilla, I needed it immediately...or so I thought) and they had a kit that included a Ram Mount X-Grip to hold the phone and a fork stem mount. The fork stem mount seems to work but I'm not 100% certain that it won't start moving around a little. Worse, the drag bars on my bike limit the adjustment so when the sun starts glaring off the screen it is difficult to quickly move the phone without stopping the bike.

Revzilla to the rescue! I ordered the U-Bolt base and installed it on my handlebars near the left grip. It mounts securely without any wiggling or wobbling. Even better, it allows the X-Grip to be clear of the bike so I can adjust the position of my phone all I want.

I subtracted a star because I consider it a bit pricey for a u-bolt, 2 screws, and 2 nuts. However, that is typical for Ram Mount items in general and at least the quality is there. It does come with a couple of black rubber caps to put over the end of the bolts/nuts but I'm pretty sure it won't be long until they fly off (which is no big deal, I don't think it looks bad without them). My only suggestion for potential owners is that you'd do well to invest in some Plasti Dip and rubberize the u-bolt where it makes contact with the handlebars. I haven't gotten around to it yet and my bars haven't been scratched but it's not worth the risk of marring the finish.

If this is a solution for your mounting problem then you can't go wrong with the Ram Mount U-Bolt Base.

Fit the DRZ perfectly. Even a good size to fit the crossbar which has a small diameter. Feels sturdy and well built.

If you ride and have a cell phone, you need this product. I have this in combination with the short arm and x-holder. It's secure and never moves. It's a must have. Now for a Bluetooth lol

Works as intended
This RAM mount does exactly what I want it to do (attach my phone to my handle bars) but I wish the U part was rubber coated as opposed to painted metal. It will scratch your handle bars if you don't put tape on them first. Minor gripe.

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!

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