The trade off IME is that HD groups are a lot more inclusive than other groups...Mostly as they are trying to sell you on the "lifestyle". However like it or not Mother Honda has her fair share of jerks too. HD riders may generally be the most arrogant but many Wing and Beamer guys aren't that far behind... Back when I rode a Yamaha V-Star I had several run ins with Wing riders and Beamerites in groups that were very noninclusive. Either let me pass or don't ride like asshats just because I dropped into formation with you.
