Have you asked BMW what has changed in these antenna, and have you asked why they are going through these changes??
No, to date I have not. Besides idle curiosity, or perhaps worry about my own EWS-equipped bike, I have no compelling need to know. BMW USA HQ happens to staff a phone-equipped English-speaking dealer-only technical desk. We try to limit our contacts with them to compelling needs, and consider it bad form to ask the tech desk to pursue such questions when compelling need is absent. Please see my earlier post where I explain in brief the simple reality of what happens when I need a ring antenna for a particular bike: I access a current dealer-only catalog, determine a current part number and pull the trigger. When new information deserving of illumination becomes known to me, I will try to pass it on. BMW has come out with five generations of ring antenna; in the next few years there may be as many more. At some point one would expect a dealer operating under real-world time scarcity to fall back on the basic process described above: simply look it up and sell it.
