RAM Mounts Stem Base 4.2 5 6 6
Wrong size plug for the application - but great unit otherwise So I went through the online parts finder to select the right application for my bike - a 2004 Honda VTR1000. The base arrived and the plug was the wrong size - too small for the opening in the stem. I solved the problem by whittling the top cylindrical bit to size with an Xacto knife.... a long and painful process, but effective. Once I'd done that, the base worked as advertised. Be warned - don't trust the online parts guide. Double-check all the measurements. October 6, 2014
Great product The perfect way to mount your cell or gps to your center stem and still be versitle enough to move around. June 16, 2014
Looks good and works better I was skeptical of how the mount would hold within the stem of my bars. But once I installed it there was nothing that will make it come out. Was lifting the bike up while pulling on it. I enjoyed this part but some might see this as a negative. It does not come ready to fit, you must essentially build it so that it fits your bike perfectly. I accidentally butchered my cuts on the rubber mount due to my rush but it still worked out just fine. Make sure you take your time and measure your cuts before slicing it, otherwise there's no second chance. Took me maybe 5 min to "build" and another 30 sec to install. Its hard to mess up but its possible so take your time. Highly recommend!!! May 20, 2014
Sturdy fairish price good buy Easy to install except on the plastic pecies you are suppose to use the biggest one that fits well they all have a excess plastic chunk on the side I had to sand down May 19, 2014
Almost Perfect The mount works adequately, and holds my Galaxy S3 steady.....at least so far. I can still rotate the mount in the steering stem w/o much effort though. I would be completely satisfied if the mount was LOCKED in place and did not rotate at all, however, it works as advertised and the price is reasonable. I recommend this mount for anyone with a sportbike that gas clip-ons and limited space behind their fairing October 21, 2013
Best solution for gadget mounts This is probably the best solution for any sort of phone/gps mount, it isn't just my opinion, it's the opinions of most of the forums I visit also. Simple to use, simple to install and RAM quality. I've lowsided with my phone rigged up on a RAM Finger Grip and it stayed put, did not budge. The only con to this style of installation is that temp changes will loosen the base a bit. Simple fix is to just simply turn it a few more times or use a longer bolt/nut through the yolk and clamping it down. April 5, 2013
