Just got mine in the mail yesterday, quick shipping! I am goint to play around with mounting them on my bark busters rather than on the bars... If that won't work than I will try a more conventional set up. Once done Will post some pics.

But many older models actually have the mirror bolt through the lever, so they are a real mixed bag of what thread/ length/ etc would be required.

Anyway, 10mm x 1.5 adapters are in the works, probably at least a month out though. Not sure how to approach others.

Couldn't you do a mirror stalk mount (the ball with the offset base and 10mm though-hole) and a handful of different cap screws?

That's what we sell currently.

The function is good, but I think it would be more elegant to have an offering that puts the ball directly into the existing mirror mount.

agreed, but the combinations or thread pitch and length needed is staggering.

You could take one of these: http://www.ram-mount.com/CatalogResu...5/Default.aspx

(ball with 1/4-20 female threads)

and come up with a set of studs. You may have to retap it to metric.

I thought there was a ball with a through hole with a countersunk well for a screw, or was that the delta faucet field-expedient fix?

There is, but it's 8mm, for bar clamp bolts.

We considered using that, but it requires stocking another part. So, what is in the works is a 10mm x 1.5 pitch adapter that threads onto the 10mm x 1.25 pitch ball we already stock. This will work for a variety of F800 and R1200 models, the rest will have to use the offset plate. We'll tune up the website on how it helps people select different options as well.

If anyone has a handle on a better plan, I'm all ears! It's been hard to track down reliable information on BMW thread pitch for different models, and our local dealer hasn't been much help.

I put 700 miles of testing these mirrors on the 800GS this weekend across a range of twisty backroads, dirt roads, jeep trails, dualsport hero sections, and superslab.

I'll do a detailed review at some point, but here are some quick notes:

First off, I love the concept. It's one of those parsimonious "duh, why didn't I think of that?" ideas. Kudos to Ned for seeing it to production.

On the 800GS, this mirror will almost never (at least under the setup variables that I've tried) be as "clear" (WRT vibration) as the stock BMW mirrors. When you feel the heft of a stock mirror, that should be pretty obvious. That having been said, with playing around to find a good setup, it is absolutely usable and leagues better than any other folding/micro mirror that I've ever tried.

I first tried the "U" bolt mounting base, just inboard of the stock mirror perch. I left the stocker on just for side-by-side comparisons. It was pretty good at low speeds, but got vibey around 40mph or so -- so much so that it really wasn't usable any more.

I was hoping to switch to a mount that threaded in to the stock mirror mount, but couldn't find a suitable combination of adaptors so I went with the 11mm offset ball and a 10x1.5 metric stud in the stock mount.

The results were pretty much identical to the U bolt. It didn't really seem to matter how much I cranked down on the arm, and switching between short and long arms didn't change much, either. There were certain gear/speed harmonics that were better or worse, but at upper backroad speeds, there was a buzz that shook the image. One thing that I noticed was that two fingers on the stalk would smooth it right out to stock mirror levels. A couple of stick on wheel weights may break the harmonic on this bike.


The other problem I was having was that the mirror would "fold" in toward me and down over moderate road bumps. A quick flick would return it to position, but it got tiresome doing it every few minutes or so. Cranking the arm down seemed to have zero effect.

The mirror was very consistent in the direction that it would fold, and I ended up coming up with a solution that got rid of the folding problem, and vastly improved the vibration -- to the point that it's almost as clear as the stock mirror at speeds up to 65 or so.



(sorry for the crappy cell phone pic)

I don't know if you can make out what I've done, but if you imagine that the RAM mount has about 180degrees of freedom in one plane (laterally, if you're looking at the screw), and very little (maybe, 30 degrees or so) in the other plane (toward/away from the screw), I set the arm so that the arm itself limited the ability of the mirror to flop toward me.

This cured the flopping completely, and made probably a 90% improvement in the vibrations overall. The one downside that I can see is that in the event of a branch strike, there's not a lot of freedom for the mirror to self-rotate (flop) out of the way. It is however still completely easy to rotate the mirror into the "stowed" position behind the windscreen.

The other curiosity I noted came on the slab ride home from the dualsport -- up to about 65 or so, the mirror was perfectly usable but then got very, very vibey (like, paint-shaker). You could tell if a vehicle was right there, but better ID at any distance was absolutely impossible. Then, above 75mph, things smoothed out to literally stock mirror levels. My assessment is that the wind pressure was providing the "two fingers" worth of pressure that would smooth the mirror out at any speed, as I had noted previously. This may be why riders on enduro type bikes report such good results with the mirror -- because of fairing design, they reach stabilizing wind pressures at much lower speeds. Just a hunch, but something to think about and perhaps playing with different positions WRT the fairing may make things better/worse on the bigger bikes.


So, net result? The stockers will be off my bike indefinitely. My riding is mixed enough to find the slight tradeoff in vibes worth the foldable/crash resistant features. If I were going on a long pavement-only ride (don't see that ever happening) I would probably put the stockers back, and if I were a heavy road commuter/someone who really needed to know whether that car 3/4 of a mile back was a cruiser or not, I'd probably leave a stocker on there. For me, though, these fit the bill.

Thanks, Ned!

Great review! I'd hate to see your "detailed" version...

One thought to add- I found that wheel balance is critical to vibration issues (on whatever kind of mirror, but I think any folding design is more susceptible). If you have a relatively narrow range where the picture isn't clear, it seems likely that is the speed where an out of balance wheel and the harmonic frequency of the mirror coincide.



Maybe try the tape/ plasticote/ whatever treatment and see if it improves the folding issue?

Anyway, glad you like them!

Today 70 miles of off road today. Not once did I have to adjust cuz the mirror fell. Wife was with me so I wanted to be able to peek at her time to time, so I left it up.

My set up is stud mount, long arm on my 950SE. If you see the bars come up that is a jump on a water bar (20-40 mph). When I stop to check on wife in the traffic, you can see the mirror. Trust me it is in the same spot as I started.

Has anybody thought of using Loctite on the stud ball? I notice I can rotate my ball with the mirror. Only see it as an issue for the Left side mirror. Or could be if I hit a branch. I was thinking just some blue loctite would take care of that. Not enough threads to put a jam nut on.

I do too. It works much better this way.

i installed my ball by putting locktite blue stick on the thread and then clamping on the arm and using that to tighten the ball. ram does not provide a flat spot on the ball mount to grab & tighten it so i figured they want use to use the arm as a lever. it's solid.

Blue balls....in this context it is a good thing.

Thanks!

I was fortunate enough to get my hands on a set of these in person today from Ned. (one of the many advantages to living in C. Springs I guess) Great guy and has developed an incredible product. So far have just used them on the ride home and think they're great. I'm looking forward to getting out for some more time in (or out) of the saddle Saturday to see how they hold up! Thanks again Ned!!

Just ordered a pair for my 1150GS. I didn't see any replies or pics from anyone who has mounted them on an 1150. I just used the suggestions from the "Build Your Mirror" but am curious to know if anyone has them mounted on an 1150.

If I find that I might need these do you have a source and part #? Thanks.

I'm not aware of where to buy these, but I'll have them available later in the summer.
