Not surprising at all. The few times that's happened on forums I frequent (and not all of them are BMW bike forums) - whoever responded gets deluged with every complaint anyone ever had about the company they represent.
Just curious, how long have you been an MOA member? BMW has certainly put apparel ads in the Owners News in the past. It seemed like they wanted to sell stuff to us. I suspect BMW-Motorrad-USA runs hot and cold on apparel - at times they had travelling trailers with fashion shows, at other times it just seems to get stagnant and a small supply is pushed onto the dealers and the dealers are expected to market it. The last apparel manager I knew was a real enthusiast and real rider, and he would solicit ideas for new gear when he met people in person. He is no longer with BMW and I don't know who (if anyone) took his place.
As Randy pointed out - part of the problem BMW-Motorrad-USA has is the competition. It IS excellent, especially almost anything from RiderWarehouse (Aerostich parent company) and the prices while not inexpensive, are a bargain when the actual functionality and long-term use of the garment is considered. Since RiderWarehouse offers repair services and custom fits for most of their products, that makes it even harder for BMW to sell a competing product at an even higher price without those benefits. The BMW stuff is nice - but they don't really make a lot for the average US BMW rider, they seem to pattern them on slender-tall euro BMW riders.
FWIW - instead of begging for it - visit RiderWarehouse's website and ask for a catalog. You'll find some very good and functional stuff there at fair prices, with most of it made in the USA.
