I've belonged to the BMW MOA for about 20 years, and as mentioned, there is less emphasis on the old airhead bikes. but there is a lot of useful info on touring.
I have been a member of the Airheads group for about 14 years, and there is a lot of technical info on the airhead bikes, but I personally don't look at much of the monthly newsletter any more, I have grown tired of some of the 'rubbish' that is published there.
That compounded with the Arizona 'air marshall' is a complete waste of the earth's resources,
let's just say that I won't be invited to any more tech days, or any other gatherings this group has.
