IMHO regardless of the ride everyone (for the most part)appears to be welcome here, which is good.
I do think that the technical stuff should stay with the BA/SM bikes. (as others have pointed out) There are already technical forums for the other bikes.
And we have the members rides section which does not appear to discriminate by brand or model. and there is some pretty cool stuff on there.
