BRCOVAN Metal Motorcycle Fork Stem Mount Base with 1'' TPU Ball for Stem Holes 12mm to 25.4mm in Diameter, Compatible with RAM Mounts B Size 1 Inch Ball Double Socket Arm

This was Super easy to install and beats my original stem mount that came with my ram mount. So much stiffer than the flimsy expanding rubber mounts. It does cause more vibration on the phone though. the mount was plenty long and seems to be sturdy. I feel much more confident in it holding my phone, 20 bucks well spent.

I have been using the RAM steering stem ball mount for years for GoPro videos on both a 2011 GSX-R750 and a 2003 CBR954RR. It worked fairly well but as was previously mentioned, required every other day (~ 200 miles per day of twisty roads) tightening on my weeklong trips in order to keep the GoPro aimed properly through the windscreen. The plastic cinching washer expanding the rubber collar inside the steering stem had limited friction capability to prevent rotation of the entire mount while operating the GoPro's controls. As already mentioned, installation of this metal sleeve mount was very easy. Once tightened it provided much more resistance to turning than the RAM device. However, installing and testing an i360 X3 demonstrated what appears to be a slight shortcoming. Operating the i360 controls allowed the ball to slightly rotate in its mount. The stem part did not rotate, only the ball itself. Removing the mounting bolt and placing an external #10 star washer below the existing 2 flat washers such that the star washer teeth contact the ball then reinstalling the bolt markedly improved the ball's resistance to torque/rotation. Because the new mount is more robust than the RAM, I hope videos will be smoother and clearer. dww Actual use result: After a few hundred miles of video recording (1100 miles on the bike), stem mount assembly and ball have remained tight. Compared to the thousands of video miles I've recorded with the prior mount, the resultant videos with this mount are the smoothest and clearest I've experienced.

I've used at least 6 different motorcycle steering stem mounts that work similarly in fashion to these however this one is far superior to every other design that I've ever tried. Most of them are often difficult to mount securely into the steering stem. Some are difficult to insert initially, some move around a good amount due to rubber bushings but this one is easy to setup, remains super secure, and is easy to remove. I have mixed feelings about the security Torx bolt but it's probably isolated to my use since I am frequently installing and removing because I use these to temporarily mount cameras or test gear to different motorcycles. It's a quality product and I've purchased several over the last couple of years and recommend repeatedly.

Only had about a week. So far so good. Easy to install and works good with my ram X

This fit in a 12mm hex hole just perfectly! Really is the perfect foundation for my phone holder system on my motorcycle. Would definitely purchase again. This is well made and seems very durable. So far it’s rock solid and looks great!

Good product but spendy.

People were raving about this on the ZX-4 forum, so I bought one.... and it lives up to the hype. I knew how bad the Ram Stem Mount was, so I never planned on using a Stem Mount... but this BRCOVAN Stem Mount is great (complete opposite of the Ram). I believe my Stem is 22mm and the large adapter worked perfectly, it's tight & secure. Someone here said it's soft metal, but that's actually good, so you don't mar the inside of your Stem Tube. Only the jaws seem to be soft (part that touches stem) where the wedges seem to be hard (part the screw goes into), so I think it's a sound design. It even comes with Spare O-Rings, so you'll be able to transfer this to your next bike, several years down the road. I'd probably prefer a version w/o the Security Screw (so you can mount it with standard tools), since I don't think there's a high probability of theft.

I was looking for a ball mount to install a CarPlay-connected screen to my bike for GPS directions. I used the major name brand's product in the past and was quite disappointed. It tore the rubber inserts, never tightened down enough to not turn in the stem, and thought it was too expensive for the low quality part. The BRCOVAN stem mount is much higher quality than the other mount. The internals that go into the stem are metal and of decent quality (better than expected from a no-name brand) and tighten down firmly. The ball cannot be spun when it is tight. The ball itself appears to be well manufactured with no rough spots from manufacturing. I believe it's textured to help grip, but doesn't have casting lines from the mold like that other brand tends to have. All in all I am quite satisfied with this product that I felt I could reasonably have expected to return it for quality concerns when I ordered it.
