The upper arms break more frequently than the lowers- which have been reported to break at varying frequency with everything from the stock windscreen to the biggest CeeBailey and Aeroflow stuff. Large windscreens (especially with a flip up), strong wind gusts at speed, and vibrations from either screen design or rough roads seem to be associated with many but not all of the reported breaks of stock arms.
There are two high quality upper arms in the aftermarket- from West Tool and Beemer Boneyard, as well as the lower noted here from Beemer Boneyard, also a high quality part. AKAIK, none of these parts has ever been reported to break- they are far superior in construction to stock.
My take on this is that if you've ever broken an arm, you ought to replace with one of the aftermarket ones which are no more expensive than stock. Also, if you notice screen vibration, ride in gusts or plan to, or have one of the big, flip up shape screens, than you might want to replace the stock upper for insurance before it breaks- I did. Personally, I think replacing the lower for insurance is most likely a bit of overkill but for sure it will get you a bulletproof solution to possible breakage. And of course, if you break a lower, use this one as a replacement.
Thanks for the input,,Would be nice to here how your install goes and what you think of them when you get them,,Tim
BTW - curious, per: http://forums.bmwmoa.org/showthread.php?46055 - what is the year and model (assume an RT..) of your bike?

Hi Guys, haven't been on the board for awhile now, just noticed this thread regarding replacement arms for the often breaking 'upper' arms. I went thru a couple of sets of uppers before I got fed up and started making my own replacements from stainless steel using the OEM German teflon bushings to complete the unit.
I have been making them for friends on the forum for a few years now, and have a couple of pair sitting on my bench if anyone would like a set. They are lazer cut from stainless steel, hand polished and painted with an industrial semi gloss black to cut down any reflections. These will NEVER break. I charge what it costs me to make them...plus the cost of the OEM bushings, and shipping. $ 70.00 a pair shipped in the US or Canada.
Here is a picture of the finished product...
PS. photography isn't my forte
