BMW doesn't care Robert. Supplying parts for old obsolete bikes is probably a PITA to them.
My guess is there's some other vendor making repops for them anyway just like Huggett makes the slingers for Vech, Bob's, and MAX.
I've heard over and over about "I like BMW because I can get parts for the old bikes"
I no longer buy that line.
